GENERAL DESCRIPTION
The P8M648YL, P8M648YLE, P16M6416YL, and
P16M6416YLE 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.
_______________________________________________
ABSOLUTE MAXIMUM RATINGS:
Voltage on Vcc Supply relative to Vss...................-1 to +4.6V
Operating Temperature TA (Ambient) .............25 ° to +70 °C
Storage Temperature .........................................-55 to +125 °
Power Dissipation…………………………………………8 W
Short Circuit Output Current…………………………..50 mA
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.
