Overview
Fast clock rate: 250/200MHz
The EM6AA160 SDRAM is a high-speed CMOS
double data rate synchronous DRAM containing 256
Mbits. It is internally configured as a quad 4M 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

Four internal banks, 4M x 16-bit for each bank
Programmable Mode and Extended Mode registers

and
. Read and write accesses to the SDRAM
CK
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 EM6AA160 provides programmable
Read or Write burst lengths of 2, 4, or 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, EM6AA160

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.
