Abstract :
A GaAs 1 K*4 static self-timed random-access memory (SSTRAM) with input and output latches and internal write-pulse generation has been designed, fabricated, and tested. Fully functional SSTRAMs have been obtained, with a worst-case clock access time (equal to read and write cycle time) of 3.6 ns for a 1.9-W device. This part is manufactured using three levels of interconnect metallization and a novel high-margin enhancement-depletion (HMED) process, and utilizes many innovative circuits.<>
