1. GENERAL DESCRIPTION
W9425G6JB is a CMOS Double Data Rate synchronous dynamic random access memory (DDR
SDRAM), organized as 4,194,304 words
× 4 banks × 16 bits. W9425G6JB delivers a data bandwidth
of up to 400M words per second (-5) compliant to the DDR400/CL3 specification.
All Input reference to the positive edge of CLK (except for DQ, DM and CKE). The timing reference
point for the differential clock is when the CLK and CLK signals cross during a transition. Write and
Read data are synchronized with the both edges of DQS (Data Strobe).
By having a programmable Mode Register, the system can change burst length, latency cycle,
interleave or sequential burst to maximize its performance. W9425G6JB is ideal for main memory in
high performance applications.
