Introduction date: 1971
Type: 320-bit MOS RAM and 4-bit output port.
Memory: 80 x 4-bit
Technology: P-channel silicon gate MOS technology
History: The 4002 was designed to be used with other MCS-4/40 devices such as the 4004 CPU.
The chip was available in two different metal options 4002-1 and 4002-2 this was to make it possible to extend the chip selection so that 4pcs of 4002 chips could be connected to the 4004 CPU without any external chip selection logic.
