摘要： A semiconductor memory device includes a plurality of memory blocks formed of a flash memory. The semiconductor memory device further includes a rewriting monitor circuit for memorizing the number of times of data rewriting in each of the memory blocks, and a switching circuit for switching a memory block selection address. When the number of times of rewriting in a first memory block which is a rewriting request object exceeds a predetermined value, data in a second memory block is transferred to the first memory block. Data to be written is written to the second memory block. Therefore, it is possible to increase the number of times of rewriting in the flash memory.

摘要： In an input protection circuit, a bipolar protection device is constituted of a semiconductor substrate of a first conductivity type, a first diffused layer of a second conductivity type formed in the substrate and connected to an input signal pad, a second diffused layer of the second conductivity type formed in the substrate to extend in parallel to the first diffused layer but separately from the first diffused layer by a first space, and a third diffused layer of a high impurity concentration and of the first conductivity type formed in the first space in the substrate to extend in parallel to the first and second diffused layers, in junction with the second diffused layer but separately from the first diffused layer. When a backward biasing voltage is applied, the thickness of a depletion layer formed is made large, so that generation of hot carriers is minimized. Thus, increase of a leakage current caused because hot carriers generated by application of an overvoltage were injected into a field oxide film, can be prevented.
