Abstract
PURPOSE:To enable the write-in in one bit, cancell the processing required for edit of memory data, and to make efficient the data processing, by setting the desired address to the register indicating an arbitrary bit-address in word. CONSTITUTION:The bit wirte-in mode is provided, the memory address written in one bit is set to the address registers 4, 4', and the address is read out and set to the readout register 3. When the data from the memory 1 is set to the register 3, the write-in pulse signal is produced from the memory control section 1', the bit address given in advance and the one bit write-in data are written in the bit location of the memory 1 designated with the bit selection address decoder 5, and in other bits, the content of the register 3 is written in the memory 1 as it is. Thus, the one- bit write-in to the memory 1 is made.
