摘要： The life of a semiconductor memory device can be prolonged by using a plurality of memory cells and decreasing the stress applied to the dielectric film of the memory cells storing a data value "1." This is achieved in the present invention by decreasing the number of rewritings required to retain stored data. Specifically, the present invention utilizes a reverse and rewrite means to reverse and rewrite data back into memory cells after being read, memory means for memorizing a signal indicating whether the currently stored data is in a reversed state, and judging means for judging whether the data should be reversely output.

摘要： The present invention extends the reading range between a contactless type information medium (semiconductor integrated circuit) and a reader/writer, which exchanges data in contactless communications with the contactless type information medium, and enables a stable data exchange even if the power supply voltage is lowered when data is returned from the contactless type information medium to the reader/writer. Specifically, when data is returned from the contactless type information medium, the data to be returned is held in the logic circuit section 200 capable of operating at a lower voltage than the non-volatile memory circuit section 300, and the reset detection lower limit voltage to be used by the reset generating circuit 160 during the data-returning period is set to be lower than that during periods other than the data-returning period.
