DESCRIPTION
The
ICSI
IC42S32400 and IC42S32400L is a high-speed
CMOS configured as a quad 1M x 32 DRAM with a
synchronous interface (all signals are registered on the
positive edge of the clock signal,CLK).
Each of the 1M x 32 bit banks is organized as 4096 rows
by 256 columns by 32 bits.Read and write accesses start
at a selected locations in a programmed sequence.
Accesses begin with the registration of a BankActive
command which is then followed by a Read or Write
command
The
ICSI
IC42S32400 and IC42S32400L provides for
programmable Read or Write burst lengths of 1,2,4,8,or
full page, with a burst termination operation. An auto
precharge function may be enable 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.
By having a programmable 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.
