Abstract :
Multilevel dynamic storage employing refreshing schemes potentially allows very compact synapses with fast read and write operations. A circuit implementation is described which performs an 8-b to 10-b transmission of dynamically stored value and a 2-MHz, successive approximation, A/D→D/A (analog-to-digital→digital-to-analog) conversion. The synapse size is 105 μm×75 μm for a 2-μm process. This implementation is capable of bandwidths in the low megahertz (1 to 20 MHz)
