This paper details an array of switch resistor based memristor emulators with integrate & fire based neuron ASIC for the development of memristor based pattern recognition. The designed ASIC has 4 memristor emulators with a conductance range from 195 nS to 190 uS; processing has been planned to be off-chip to get the freedom of programmability of any function in ASIC. The ASIC has 2 integrate and fire (I & F) neuron circuits which are planned to be used in conjunction with memristors in a large multiple chip network for pattern recognition. This paper explains the memristor emulator, I & F neurons and an algorithm of pattern recognition simulated in Ltspice. The ASIC has been fabricated in AMS 350nm process.
