    摘要: A semiconductor file memory device, and an information processing system incorporating the device, uses flash memories to achieve fast file access performance. The file memory device includes a parallel arrangement of memory element groups having a unit erasure block size greater than the data bus width of the memory device, and a data access width smaller than the data bus; a file division unit for dividing file data having one or more unit storage data blocks into combined blocks that include a combination of arbitrary unit storage data blocks; a data distribution unit for arbitrarily combining data on the data bus having a unit data size equal to the data access width, and for making the combined data correspond to an arbitrary combination of memory element groups equal in number to the unit size data; and a control unit for controlling the data distribution unit so that each combined block is stored in the file memory device based on a correspondence between the combined block and arbitrary combinations of memory elements.

    摘要: Using a comparatively low supply voltage of, e.g., +5V and a minus gate voltage, the voltage difference between the gate of an MNOS transistor and a P-type well region in which a MNOS transistor is formed is relatively changed to execute the writing and erasing of the MNOS transistor. Thus, the potential of an N-type semiconductor substrate can be fixed to a comparatively low potential, e.g., about +5V, so that a P-channel MOSFET formed on the semiconductor substrate operates with an ordinary signal level. Consequently, an EEPROM having peripheral circuits constructed of CMOS circuits can be provided. Accordingly, reduction in the power consumption of the EEPROM can be attained.

    摘要: Flash memory is rapidly decreasing in price. There is a demand for a new memory system that permits size reduction and suits multiple-value memory. A flash memory of AND type suitable for multiple-value memory with multiple-level threshold values can be made small in area if the inversion layer is utilized as the wiring; however, it suffers the disadvantage of greatly varying in writing characteristics from cell to cell. Another promising method of realizing multiple-value memory is to change the storage locations. This method, however, poses a problem with disturbance at the time of operation. The present invention provides one way to realize a semiconductor memory device with reduced cell-to-cell variation in writing characteristics. The semiconductor memory has a source region and a drain region, which are formed parallel to each other, and an assist electrode which is between and parallel to the source and drain regions without overlapping, so that it uses, at the time of writing, the assist electrode as the assist electrode for hot electrons to be injected at the source side and it uses, at the time of reading, the inversion layer formed under the assist electrode as the source region or the drain region.
