4002
| 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 | |
| Number of transistors: | ||
| 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. | |
| Second source: | National Semiconductors was the only second source. |
