Power Supply

Overview

The EM6AA320 DDR SDRAM is a high-speed CMOS

double data rate synchronous DRAM containing 256

Mbits. It is internally configured as a quad 2M x 32

DRAM with a synchronous interface (all signals are

registered on the positive edge of the clock signal, CK).

Data outputs occur at both rising edges of CK and CK#.

Read and write accesses to the SDRAM are burst

oriented; accesses start at a selected location and

continue for a programmed number of locations in a

programmed sequence.

command, which is then followed by a Read or Write

command.

The EM6AA320 provides programmable Read or Write

burst lengths of 2, 4, 8. An auto precharge function may

be enabled to provide a self-timed row precharge that is

initiated at the end of the burst sequence.

The refresh functions, either Auto or Self Refresh are

easy to use.

In addition, EM6AA320 features programmable DLL

option. By having a programmable mode register and

extended mode register, the system can choose the

most suitable modes to maximize its performance.

These devices are well suited for applications requiring

high memory bandwidth, result in a device particularly

well suited to high performance main memory and

graphics applications.
