In a parallel operational processing device having an operational processing unit arranged between memory blocks each having a plurality of memory cells arranged in rows and columns, the respective columns of each memory block are alternately connected to the operational processing units on the opposite sides of the memory block. By selecting one word line in one memory block, data can be transferred to two operational processing units. The number of the word lines selected per one operational processing unit is reduced, and power consumption is reduced. The bit operation units and sense amplifiers / write drivers of the operational processing units have arrangement pitch conditions mitigated and are reduced in number, and an isolation region between the memory blocks is not required and the layout area is reduced. Thus, the parallel operational processing device with a layout area and the power consumption reduced, can achieve a fast operation.

A portable data storage device includes a USB controller, a master control unit and a NAND flash memory device. The master control unit receives data to be written to logical addresses, and instructions to read data from logical addresses. It uses a memory address mapping table to associate the logical addresses with the physical addresses in the memory device, and writes data to or reads data from the physical address corresponding to the logical address. The mapping is changed at intervals, so that different ones of the physical address regions are associated at different times with the logical addresses. This increases the speed of the device, and also means that no physical addresses are rapidly worn out by being permanently associated with logical addresses to which data is written relatively often.
