64MX 64 UNBUFFERED SDRAM SODIMM
SDRAM SODIMM MODULE
512 MByte (64M x 64) SDRAM Unbuffered 144 Pin SODIMM LOW PROFILE (1.03 inch height)
General Description:
This memory module is a high performance 512 Megabyte Unbuffered synchronous dynamic RAM module organized as 64M x 64 in a 144 pin Small Outline Dual In-Line Memory Module (SODIMM) package. The module utilizes eight (8) 8Mx4X16 512MbitSDRAM1 devices in a TSOP II 400 mil package. A 256 Byte Serial EEPROM contains the module configuration information. The EEPROM can be configured to a customer's specifications. These modules offer substantial advances in SDRAM operating performance, including the ability to synchronously burst data at a high rate with automatic column-address generation, interleave between internal banks in order to hide precharge time, and the capability to randomly change column address on each clock cycle during burst.
Features:
High density: Cycle time: 512 MB (64M x 64) 10 ns (100 MHz) 7.5 ns (133 MHz) JEDEC Standard 144 Pin Unbuffered SDRAM SODIMM Pinout PC133 and PC100 Compliant Single power supply of 3.3V 10% Serial Presence Detect LVTTL Compatible I/O and Clock Unbuffered Control and Address Lines Auto Precharge handled by SDRAM Devices Refresh 8K rows every 64ms Programmable Burst Type, Burst Length and CAS Latency of SDRAM Devices Internal Pipeline Operation Fully Synchronous - all signals registered on positive edge of system clock Package Height: 1.03 inches (+/- 10mils)

64M X 64 UNBUFFERED SDRAM SODIMM
Operating Features:
The SDRAM SODIMM utilizes a clock input for the synchronization. Each operation of the SDRAM is determined by commands and all operations are referenced to a positive clock edge. CAS Latency defines the delay from when a Read Command is registered on a rising clock edge to when the data from the Read Command becomes available at the outputs. The CAS latency is expressed in terms of clock cycles. This specific DIMM supports 3 and 2 clock cycles. The burst mode is a very high-speed access mode utilizing an internal column address generator. Once a column address for the first access is set, following addresses are automatically generated by the internal column address counter. All control and address signals are supplied from the chipset through an unbuffered path to the SDRAMs. There are two clock signals supplied by the motherboard to synchronize the SODIMM.
