1971
P-channel silicon gate MOS technology 320-bit MOS RAM
and 4-bit output port
80 x 4-bit
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. |
