DESCRIPTION
The
I
S
SI
I
S42S32800B
is a high-speed
CMOS
configured as a quad 2M x 32 DRAM with a
synchronous interface (all signals are registered on the
positive edge of the clock signal,CLK).
Each of the 2M x 32 bit banks is organized as 4096 rows
by 512 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
I
S
SI
IS42S32800B
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 o
r
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.
