GENERAL DESCRIPTION
Am29DS323D family consists megabit, volt-onl flas devices, 2,097,152 words bits each 4,194,304 bytes bits each. Word mode data appears DQ0-DQ15; byte mode data appears DQ0-DQ7. device designed programmed in-system with standard volt supply, also programmed standard EPROM programmers. device available with access time devices offered 48-ball FBGA package. Standard control pins-chip enable (CE#), write enable (WE#), output enable (OE#)-control normal read write operations, avoid contention issues. device requires only single volt power supply both read write functions. Internally generated regulated voltages provided program erase operations. removal EEPROM devices. will also allow system software simplified, will perform functions necessary modify data file structures, opposed single-byte modifications. write update particular piece data phone number configuration data, example), user only needs state which piece data updated, where updated data located system. This user-written software must keep track data location, status, logical physical translation data onto Flash memory device memory devices), more. Using DMS, user-written software does need interface with Flash memory directly. Instead, user's software accesses Flash memory calling only functions. provides this software simplify system design software integration efforts. device offers complete compatibility with JEDEC single-power-supply Flash command standard. Commands written command register using standard microprocessor write timings. Reading data device similar reading from other Flash EPROM devices. host system detect whether program erase operation complete using device status bits: RY/BY# pin, (Data# Polling) DQ6/DQ2 (toggle bits). After program erase cycle been completed, device automatically returns reading array data. sector erase architecture allows memory sectors erased reprogrammed without affecting data contents other sectors. device fully erased when shipped from factory. Hardware data protection measures include detector that automatically inhibits write operations during power transitions. hardware sector protection feature disables both program erase operations combination sectors memo programming equipment. device offers power-saving features. When addresses have been stable specified amount time, device enters automatic sleep mode. system also place device into standby mode. Power consumption greatly reduced both modes.
Simultaneous Read/Write Operations with Zero Latency
Simultaneous Read/Write architecture provides simultaneous operation dividing memory space into banks. device improve overall system performance allowing host system program erase bank, then immediately simultaneously read from other bank, with zero latency. This releases system from waiting completion program erase operations.

Simultaneous Read/Write Operations with Zero Latency
This device capable reading data from bank memory while programming erasing other bank memory. erase operation also suspended read from program another location within same bank (except sector being erased). Figure shows read write cycles initiated simultaneous operation with zero latency. ICC6 ICC7 Characteristics table represent current specifications read-while-program read-while-erase, respectively.
Standby Mode
When system reading writing device, place device standby mode. this mode, current consumption greatly reduced, outputs placed high impedance state, independent input. device enters CMOS standby mode when RESET# pins both held (Note that this more restricted voltage range than VIH.) RESET# held VIH, within device will standby mode, standby current will greater. device requires standard access time read access when device either these standby modes, before ready read data. device deselected during erasure programming, device draws active current until operation completed. Characteristics table represents standby current specification.

Characteristics table represents automatic sleep mode current specification. RESET# tied system reset circuitry. system reset would thus also reset Flash memory, enabling system read boot-up firmware from Flash memory. RESET# asserted during program erase operation, RY/BY# remains (busy) until internal reset operation complete, which requires time tREADY (during Embedded Algorithms). system thus monitor RY/BY# determine whether reset operation complete. RESET# asserted when program erase operation executing (RY/BY# "1"), reset operation completed within time tREADY (not during Embedded Algorithms). system read data after RESET# returns VIH. Refer Characteristics tables RESET# parameters Figure timing diagram.
RESET#: Hardware Reset
RESET# provides hardware method resetting device reading array data. When RESET# driven least period tRP, device immediately terminates operation progress, tristates output pins, ignores read/write commands duration RESET# pulse. device also resets internal state machine reading array data. operation that interrupted should reinitiated once device ready accept another command sequence, ensure data integrity. Current reduced duration RESET# pulse. When RESET# held VSS±0.3 device draws CMOS standby current (ICC4). RESET# held within VSS±0.3 standby current will greater. Table

SecSi(Secured Silicon) Sector Flash Memory Region
SecSi (Secured Silicon) Sector feature provides Flash memory region that enables permanent part identification through Electronic Serial Number (ESN). SecSi Sector Kbytes length, uses SecSi Sector Indicator indicate whether SecSi Sector locked when shipped from factory. This permanently factory cannot changed, which prevents cloning factory locked part. This ensures security once product shipped field. offers device with SecSi Sector either ocke ckabl tory-locked version always protected when shipped from factory, SecSi Sector Indicator permanently "1." customer-lockable version shipped with unprotected, allowing customers utilize that sector manner they choose. customer-lockable version SecSi Sector Indicator permanently "0." Thus, SecSi Sector Indicator prevents customer-lockable devices from being used replace devices that factory locked. system accesses SecSi Sector through command sequence (see "Enter SecSiSector/Exit SecSi Sector Command Sequence"). After system written Enter SecSi Sector command sequence, read SecSi Sector using addresses normally occupied boot sectors. This mode operation continues until system issues Exit SecSi Sector command sequence, until power removed from device. power-up, following hardware reset, device reverts sending commands boot sectors instead SecSi sector. Factory Locked: SecSi Sector Programmed Protected Factory factory locked device, SecSi Sector protected when device shipped from factory.

Notes: Typical program erase times assume following conditions: 25°C, VCC, 1,000,000 cycles. Additionally, programming typicals assume checkerboard pattern. Under worst case conditions 90°C, 1,000,000 cycles. typical chip programming time considerably less than maximum chip programming time listed, since most bytes program faster than maximum program times listed. pre-programming step Embedded Erase algorithm, bytes programmed before erasure. System-level overhead time required execute two- four-bus-cycle sequence program command. Table further information command definitions. device minimum erase program cycle endurance 1,000,000 cycles.
