GENERAL DESCRIPTION

The UT51C164 is high speed 5V EDO DRAMs organized as 256K bit X 16 I/O and fabricated with

the CMOS process. The UT51C164 offers a combination of unique features including : EDO Page

Mode operation for higher bandwidth with Page Mode cycle time as short as 14ns. All inputs are

TTL compatible. Input and output capacitance is significantly lowered to increase performance and

minimize loading. These features make the UT51C164 suited for wide variety of high performance

computer systems and peripheral applications
