Because synchronous device, address, data inputs, read/write control inputs captured rising edge input clock. Burst order control (LBO) must tied power rail proper operation. Asynchronous inputs include Sleep mode enable (ZZ) Output Enable. Output Enable used override synchronous control output drivers turn RAM's output drivers time. Write cycles internally self-timed initiated rising edge clock input. This feature eliminates complex offchip write pulse generation required asynchronous SRAMs simplifies input signal timing. GS8322Z18/36/72-xxxV configured user operate Pipeline Flow Through mode. Operating pipelined synchronous device, addition rising-edgetriggered registers that capture input signals, device incorporates rising edge triggered output register. read cycles, pipelined SRAM output data temporarily stored edge-triggered output register during access cycle then released output drivers next rising edge clock. GS8322Z18/36/72-xxxV implemented with GSI's high performance CMOS technology available JEDECstandard 119-bump, 165-bump 209-bump package.

Clocking Deassertion Clock Enable (CKE) input blocks Clock input from reaching RAM's internal circuits. used suspend operations. Failure observe Clock Enable set-up hold requirements will result erratic operation. Pipeline Mode Read Write Operations inputs (with exception Output Enable, Linear Burst Order Sleep) synchronized rising clock edges. Single cycle read write operations must initiated with Advance/Load (ADV) held low, order load address. Device activation accomplished asserting three Chip Enable inputs (E1, E3). Deassertion Enable inputs will deactivate device. Function Read Write Byte Write Byte Write Byte Write Byte Write Bytes Write Abort/NOP
Read operation initiated when following conditions satisfied rising edge clock: asserted low, three chip enables (E1, active, write enable input signals deasserted high, asserted low. address presented address inputs latched into address register presented memory core control logic. control logic determines that read access progress allows requested data propagate input output register. next rising edge clock read data allowed propagate through output register onto output pins. Write operation occurs when selected, active, Write input sampled rising edge clock. Byte Write Enable inputs (BA, determine which bytes will written. none activated. write cycle with Byte Write inputs active no-op cycle. pipelined SRAM provides double late write functionality, matching write command versus data pipeline length cycles) read command versus data pipeline length cycles). first rising edge clock, Enable, Write, Byte Write(s), Address registered. Data associated with that address required third rising edge clock. Flow Through Mode Read Write Operations Operation Flow Through mode very similar operations Pipeline mode. Activation Read Cycle Burst Address Counter identical. Flow Through mode device begin driving data immediately after address clocked into RAM, rather than holding data until following (second) clock edge. Therefore, Flow Through mode read pipeline cycle shorter than Pipeline mode. Write operations initiated same way, differ that write pipeline cycle shorter well, preserving ability turn from reads writes without inserting dead cycles. While pipelined RAMs implement double late write protocol Flow Through mode single late write protocol mode observed. Therefore, Flow Through mode, address control registered first rising edge clock data required data input pins second rising edge clock.

Sleep Mode During normal operation, must pulled low, either user internal pull down resistor. When pulled high, SRAM will enter Power Sleep mode after cycles. this time, internal state SRAM preserved. When returns low, SRAM operates normally after cycles wake time. Sleep mode current, power-down mode which device deselected current reduced ISB2. duration Sleep mode dictated length time High state. After entering Sleep mode, inputs except become disabled outputs High-Z asynchronous, active high input that causes device enter Sleep mode. When driven high, ISB2 guaranteed after time tZZI met. Because asynchronous input, pending operations operations progress properly completed asserted. Therefore, Sleep mode must initiated until valid pending operations completed. Similarly, when exiting Sleep mode during tZZR, only Deselect Read commands applied while SRAM recovering from Sleep mode.

SAMPLE/PRELOAD SAMPLE/PRELOAD Standard 1149.1 mandatory public instruction. When SAMPLE PRELOAD instruction loaded Instruction Register, moving controller into Capture-DR state loads data RAMs input buffers into Boundary Scan Register. Boundary Scan Register locations associated with input pin, loaded with default state identified Boundary Scan Chain table this section datasheet. Because clock independent from Clock (TCK) possible attempt capture ring contents while input buffers transition (i.e. metastable state). Although allowing sample metastable inputs will harm device, repeatable results cannot expected. input signals must stabilized long enough meet TAPs input data capture set-up plus hold time (tTS plus tTH). RAMs clock inputs need paused other operation except capturing ring contents into Boundary Scan Register. Moving controller Shift-DR state then places boundary scan register between pins. EXTEST EXTEST IEEE 1149.1 mandatory public instruction. executed whenever instruction register loaded with logic EXTEST command does block override RAM's input pins; therefore, RAM's internal state still determined input pins. Typically, Boundary Scan Register loaded with desired pattern data with SAMPLE/PRELOAD command. Then EXTEST command used output Boundary Scan Register's contents, parallel, RAM's data output drivers falling edge when controller Update-IR state. Alternately, Boundary Scan Register loaded parallel using EXTEST command. When EXTEST instruction selected, sate RAM's input pins, well default values Scan Register locations associated with pin, transferred parallel into Boundary Scan Register rising edge Capture-DR state, RAM's output pins drive value Boundary Scan Register location with which each output associated. IDCODE IDCODE instruction causes loaded into register when controller Capture-DR mode places register between pins Shift-DR mode. IDCODE instruction default instruction loaded power time controller placed Test-Logic-Reset state. SAMPLE-Z SAMPLE-Z instruction loaded instruction register, outputs forced inactive drive state (highZ) Boundary Scan Register connected between when controller moved Shift-DR state. These instructions Reserved Future Use. this device they replicate BYPASS instruction.
