Description
The IDT7052 is a high-speed 2K 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 IDT7052 is also designed to be used in systems where on-chip
hardware port arbitration is not needed. This part lends itself to those

1. 'X' in part number indicates power rating (S or L).
2. VCC = 5V, TA = +25°C and are not production tested.
www.DataSheet4U.com3. f = 0 means no address or control lines change.
4. 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.
6. Industrial temperature: for specific speeds, packages and powers contact your sales office.
