Description
The V59C1512(404/804/164)QD is a four bank DDR
DRAM organized as 4 banks x 32Mbit x 4 (404), 4 banks x
16Mbit x 8 (804), or 4 banks x 8Mbit x 16 (164). The
V59C1512(404/804/164)QD achieves high speed data
transfer rates by employing a chip architecture that
prefetches multiple bits and then synchronizes the output
data to a system clock.
The chip is designed to comply with the following key
DDR2 SDRAM features:(1) posted CAS with additive la-
tency, (2) write latency = read latency -1, (3) On Die Ter-
mination.
All of the control, address, circuits are synchronized
with the positive edge of an externally supplied clock. I/O
s are synchronized with a pair of bidirectional strobes
(DQS, DQS) in a source synchronous fashion.
Operating the four memory banks in an interleaved
fashion allows random access operation to occur at a
higher rate than is possible with standard DRAMs. A se-
quential and gapless data rate is possible depending on
burst length, CAS latency and speed grade of the device.
Available Speed Grade:
-37 (DDR2-533) @ CL 4-4-4
-3 (DDR2-667) @ CL 5-5-5
-25A (DDR2-800) @ CL 6-6-6
-25 (DDR2-800) @ CL 5-5-5
-19A(DDR2-1066)@CL 7-7-7
