Abstract :
A new associative memory cell is described and analysed using SPICE3d1. The CMOS cell uses current summation to compute, in parallel, Hamming distances between the search key and each word in the memory. For 32 bit words, SPICE simulations of a 2 mu m process show a delay of 4 ns/bit for Hamming distances less than three.
