General Description

The 256Mb DDR SDRAM uses a double-data-rate architecture to achieve high-speed operation.

The double data rate architecture is essentially a 2n prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins.

A single read or write access for the 256Mb DDR SDRAM effectively consists of a single 2nbit wide, one clock cycle data transfer at the internal DRAM core and two corresponding n-bit wide, one-half-clock-cycle data transfers at the I/O pins.

Key Features

CAS Latency and Frequency CAS Latency 2 2.5 3 Maximum Operating Frequency (MHz) DDR400 (5) 133 166 200.
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 concurrent op.
