Abstract :
An integrated memory/logic GaAs chip designed for digital RF memory (DRFM) applications is described. Using the distributed control approach, a 750-gate logic function, including demultiplexing, multiplexing, address generation, and control circuitry, is integrated with 4 kb of on-chip static RAM. A string of these chips is the digital equivalent of a variable-length delay line. This chip, called a programmable delay line element, implements the basic DRFM storage and delay functions.<>
