Publication number: 20110267893Abstract: A non-volatile semiconductor memory determines that a given memory cell in an array is at a predetermined threshold voltage in a determination circuit by comparing a current of the memory cell with a reference current in a sense amplifier circuit. A reference current generation circuit includes a current variable device adjusting the reference current. A current adjustment amount calculator receives address information of the memory cell of which threshold voltage is determined and calculates a current adjustment amount corresponding to the address information. The current variable device adjusts the reference current based on the calculated current adjustment amount. Therefore, even when characteristics of interconnects coupled to the sense amplifier circuit, the target memory cell, and the sense amplifier vary, an offset amount between an actual threshold and an apparent threshold is eliminated to reduce electric stress applied to the memory cell in a rewrite operation.Type: ApplicationFiled: July 11, 2011Publication date: November 3, 2011Applicant: PANASONIC CORPORATIONInventors: Junichi KATO, Hideto Kotani
