Abstract

PURPOSE:To enable excellent data transfer with a simple constitution when power supply is disconnected, by continuously performing the write-in to the erasable semiconductor nonvolatile memory and disconnection of power supply depending on the two state of switch. CONSTITUTION:The terminals D, C are short-circuited with one state application of the switch SW, causing the input signal applied to the write-in pulse generating circuit OSC, for data write-in to the semiconductor nonvolatile memory array MEM electrically erasable. With this switch applied to the 2nd state, the contact E is detouched and write-in and power supply are disconnected. While this, the write-in to the memory MEM has already been finished, and the data transfer at power supply disconnection with a simple constitution can be made without detecting the disconnection of power supply. This can be applied to the erase of memory, abd the readout of memory at reapplication of power supply is similarly done, and the data can be transferred in excellent manner even at disconnection and reapplication of power supply.
