Overview

The EM658160 SDRAM is a high-speed CMOS

double data rate synchronous DRAM containing 64

Mbits. It is internally configured as a quad 1M x 16

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. Accesses begin with the

registration of a BankActivate command which is then

followed by a Read or Write command. The EM658160

provides programmable Read or Write burst lengths of 2,

4, 8, full page.

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,

EM658160 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.
