Technology:   P-channel silicon gate MOS technology
Number of transistors:   2,300 (10 microns)
Addressable memory:   4096x8-bit ROM and 1280x4-bit RAM
Number of instructions:   45 with a 4 level stack and sixteen 4-bit (or eight 8-bit) registers
History:






 		   In 1969 Busicom asked Intel to design a set of chips to be used in a new high perfomance calculator.
Ted Hoff, Federico Faggin and Stan Mazor came up with a design that involved a central processing unit, 4004 (CPU)
a read-only memory, 4001 (ROM) a random access memory, 4002 (RAM) and a shift register, 4003 (I/O).
The CPU was eventually to be called a microprocessor.
Later Intel negotiated for a return of the rights for the chips, wish had gone to Busicom in the original contract.

Please see MCS-4 section for more info on chipset.
 
Second source:   National Semiconductors was the only second source to Intel 4004.
