GENERAL DESCRIPTION
The P16M648YA7 and P32M6416YA7 is a high
performance dynamic random-access 256MB module,
organized in a x64 configuration, and utilize quad bank
architecture with a synchronous interface. All signals are
registered on the positive edge of the clock signals CK0
through CK3. Read and write accesses to the SDRAM are
burst oriented; accesses start at a location and continue
for a programmed number of locations in a sequence.
Accesses begin with an ACTIVE command, which is
followed by a READ or WRITE command.

NOTES:
1. Icc is dependent on output loading and cycle rates. Specified values are obtained with minimum cycle time and the
outputs open.
2. The Icc current will decrease as the CAS latency is reduced. This is because maximum cycle rate is slower as CAS
latency is reduced.
3. Address transitions average one transition every 30ns.
4. Other input signals are allowed to transition no more than once in any 30ns period.
