Description
The 256Mb DDR SDRAM is a high-speed CMOS, dynamic random-access memory containing 268,435,456 bits.
It is internally configured as a quad-bank DRAM.
The DDR SDRAM provides for programmable Read or Write burst lengths of 2, 4 or 8 locations.
Features
- CAS Latency and Frequency
CAS Latency 2 2.5 Maximum Operating Frequency (MHz).
- DDR333 (-6) DDR300 (-66) 133 133 166 150.
- Double data rate architecture: two data transfers per clock cycle.
- Bidirectional data strobe (DQS) is transmitted and received with data, to be used in capturing data at the receiver.
- DQS is edge-aligned with data for reads and is centeraligned with data for writes.
- Differential clock inputs (CK and CK).
- Four internal banks for.
