16M X 64 / 72 UNBUFFERED SDRAM DIMM
SDRAM MODULE
128 MByte (16M x 64 / 72) SDRAM Low Profile Unbuffered 168 Pin DIMM
General Description:
This memory module is a high performance 128 Megabyte Unbuffered synchronous dynamic RAM module organized as 16M x 64 in a 168 pin Dual In-Line Memory Module (DIMM) package in two Banks. The module utilizes sixteen (16) 2Mx4X8 SDRAM (64ms Refresh) devices in a TSOP II 400 mil package. Also available with ECC option as 16M X 72 in a DIMM package that utilizes eighteen (18) 4Mx4X8 SDRAM devices. 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 DRAM 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: 128 MB (16M x 64) 128 MB (16M x 72) Cycle time: 10ns (100 MHz) JEDEC Standard 168 Pin Unbuffered SDRAM DIMM PC-100 Compliant Single power supply of 3.3V ± 10% Serial Presence Detect LVTTL Compatible I/O and Clock Unbuffered Control & Address Lines Auto Precharge and Auto Refresh Modes handled by SDRAM Devices 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: 1.20 inches
