Description
The IDT7054 is a high-speed 4K x 8 FourPort™ Static RAM designed
to be used in systems where multiple access into a common RAM is
required. This FourPort Static RAM offers increased system performance
inmultiprocessorsystemsthathaveaneedtocommunicateinrealtimeand
also offers added benefit for high-speed systems in which multiple access
is required in the same cycle.
The IDT7054 is also designed to be used in systems where on-chip
hardware port arbitration is not needed. This part lends itself to those
systems which cannot tolerate wait states or are designed to be able to

1. 'X' in part number indicates power rating (S or L).
2. VCC = 5V, TA = +25°C and are not production tested.
3. f = 0 means no address or control lines change.
www.DataSheet4U.com4. At f = fMAX, address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1/tRC, and using “AC Test Conditions” of input
levels of GND to 3V.
5. For the case of one port, divide the appropriate current above by four.
