Abstract
When the input write data is a value of a value greater than the existing data of the memory array, the semiconductor memory device enables writing of input write data to the memory array. In specific terms, the increment controllerreads the existing data from the memory array, and compares it with the write data latched to the 8-bit latch register. When the value of the write data is a value greater than the existing data, the increment controlleroutputs the write enable signal WENto the write/read controller, and executes writing of the write data latched to the 8-bit latch registerto the memory array
