GENERAL DESCRIPTION
The P8M646YLG, P16M6412YLG, are high
performance dynamic random-access 64MB and 128MB
modules respectively. These modules are 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.

Stresses beyond these may cause permanent damage to
the device. This is a stress rating only and functional
operation of the device at or beyond these conditions is
not implied. Exposure to these conditions for extended
periods may affect reliability.

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.
