GRNERAL DESCRIPTION
The T436416D SDRAM is a high-speed CMOS
synchronous DRAM containing 64 Mbits. It is internally
configured as 4 Banks of 1M 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 T436416D 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.
