Overview
The IC43R32400 DDR SDRAM is a high-speed CMOS
double data rate synchronous DRAM containing 128
Mbits. It is internally configured as a quad 1M 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.
Accesses begin with the registration of a BankActivate
command, which is then followed by a Read or Write
command.
The IC43R32400 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, IC43R32400 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.
