Abstract
A storage circuit includes a memory cell array of memory cells each including a variable resistance type element, a resistance-voltage conversion circuit RTto convert a resistance value of a memory cell MCto be read to a data voltage, a reference circuit and RTto generate a reference voltage, a sense amplifier to determine read data by receiving the data voltage and the reference voltage via first and second input terminals, respectively, and comparing both voltages with each other, and an analog buffer circuit arranged between the resistance-voltage conversion circuit RTand a first input terminal of the sense amplifier or between the reference circuit and RTand a second input terminal of the sense amplifier. Current driving capability of the analog buffer circuit is large.
