GENERAL DESCRIPTION
The P8M644YL9 and P16M648YL9 are high performance
dynamic random-access 64MB and 128MB modules
respectively. These modules are organized in a x64
configuration, and utilize dual 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 °C
Power Dissipation……………………………………4 or 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.
