Overview
The EM63B165 SDRAM is a high-speed CMOS
synchronous DRAM containing 512 Mbits. It is
internally configured as 4 Banks of 8M 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 Bank Activate command
which is then followed by a Read or Write command.
The EM63B165 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.
