VS26417801B,VS46417801B
2M,4MX64-Bit
SDRAM Module
Description
The VS26417801B and VS46417801B are 2M x 64 - bit and 4M x 64 - bit dual - in - line synchronous
dynamic
RAM
module
(DIMM).
It
is
mounted
with
8/16
pieces
of
2M
x
8
synchronous
DRAM(VG3617801BT), and each in a standard 44 pin TSOP package. The VS26417801B and
VS46417801B make high density possible without utilizing the surface mount technology on the printed
circuit board. Decoupling capacitors are mounted on power supply line for noise reduction. The module uses
serial presence detects implemented via a 2k-bit serial EEPROM component.
Features
VS26417801B, VS46417801B :
Single 3.3V (
) power supply
Utilizes 100MHz SDRAM components
Fully synchronous with all signals referenced to a positive clock edge
Programmable burst length (1,2,4,8 & Full page)
Programmable wrap sequence (Sequential/Interleave)
Automatic precharge and controlled precharge
Auto refresh and self refresh modes
I/O level : LVTTL interface
Random column access in every cycle
2048 refresh cycles/32ms
Serial Presence Detect (SPD)
JEDEC Standard pinout
Comply to Intel PC - 100 4clock unbuffered SDRAM DIMM spec.
