Enlarged color photograph of the Intel® 1601A Memory Die. Fabricated with silicon gate technology; 256 word by 8 bit electrically programmable ROM suited for uses where fast turnaround and pattern experimentation were important such as in prototype or in one of a kind systems; factory reprogrammable which allowed Intel to perform a complete programming and functional test on each bit position before delivery; inputs and outputs DDT and TTL compatible; static and dynamic operation; the 1601 uses an identical chip related to 1602, 1701 and 1702.
