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
