A Clock Enable (CEN) pin allows operation of the IDT71V3548  
to be suspended as long as necessary. All synchronous inputs are  
ignored when (CEN) is high and the internal device registers will hold  
their previous values.

Description  
The IDT71V3548 are 3.3V high-speed 4,718,592-bit (4.5 Megabit)  
synchronous SRAMS. They are designed to eliminate dead bus  
cycles when turning the bus around between reads and writes, or  
writes and reads. Thus, they have been given the name ZBTTM, or  
Zero Bus Turnaround.
