SDRAM FEMMA SODIMM MODULE
MByte (64M MByte (64M NON-ECC SDRAM Unbuffered SODIMM
This memory module high density Megabyte Unbuffered synchronous dynamic module organized 64/72 144-pin Small Outline Dual In-Line Memory Module (SODIMM) package. module utilizes sixteen eighteen 8Mx4X8 256MbitSDRAM devices TSOP package. zero delay buffer drives input clock SDRAM devices. Byte Serial EEPROM contains module configuration information. EEPROM configured customer's specifications. These modules offer substantial advances SDRAM operating performance, including ability synchronously burst data high rate with automatic column-address generation, interleave between internal banks order hide precharge time, capability randomly change column address each clock cycle during burst.

UNBUFFERED FEMMA SDRAM SODIMM
Operating Features:
FEMMA SDRAM SODIMM utilizes clock input synchronization. Each operation SDRAM determined commands operations referenced positive clock edge. Latency defines delay from when Read Command registered rising clock edge when data from Read Command becomes available outputs. latency expressed terms clock cycles. This specific DIMM supports clock cycles. burst mode very high-speed access mode utilizing internal column address generator. Once column address first access set, following addresses automatically generated internal column address counter. control address signals supplied from chipset through unbuffered path SDRAMs. supplied motherboard feeds into Phase Lock Loop (PLL) module drive sixteen SDRAMs.
