Overview
The EM63A165 SDRAM is a high-speed CMOS
synchronous DRAM containing 256 Mbits. It is
internally configured as 4 Banks of 4M word x 16
DRAM with a synchronous interface (all signals are
registered on the positive edge of the clock signal,
CLK). 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 EM63A165 provides for programmable Read or
Write burst lengths of 1, 2, 4, 8, or full page, with a
burst termination option. 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.
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 and
particularly well suited to high performance PC
applications.
