256MB 184 PIN DDR333 DDR
SDRAM DIMM With 32Mx8 2.5VOLT
Description
The JM334D643A-60 is a 32M x 64bits Double Data Rate
SDRAM high density for DDR333. The JM334D643A-60
consists of 8pcs CMOS 32Mx8 bits Double Data Rate
SDRAMs in 66 pin TSOP-II 400mil packages and a 2048
bits serial EEPROM on a 184-pin printed circuit board.
The JM334D643A-60 is a Dual In-Line Memory Module
and is intended for mounting into 184-pin edge connector
sockets.
Synchronous design allows precise cycle control with the
use of system clock. Data I/O transactions are possible
on both edges of DQS. Range of operation frequencies,
programmable latencies allow the same device to be
useful for a variety of high bandwidth, high performance
memory system applications.
Features
Power supply: VDD: 2.5V ± 0.2V, VDDQ: 2.5V ±
0.2V
Max clock Freq: 166MHZ.
Double-data-rate architecture; two data transfers per
clock cycle
Differential clock inputs(CK and /CK)
Burst Mode Operation.
Auto and Self Refresh.
Data I/O transactions on both edge of data strobe.
Edge aligned data output, center aligned data
input.
Serial Presence Detect (SPD) with serial EEPROM
SSTL-2 compatible inputs and outputs.
MRS cycle with address key programs.
CAS Latency (Access from column address) : 2.5
Burst Length (2,4,8 )
Data Sequence (Sequential & Interleave)
