<p>PROBLEM TO BE SOLVED: To set a program unit freely by making the prescribed numbers as a specified page unit when a command specifying a program unit is included based on a decoded result by a command decoding means. SOLUTION: This memory is characterized in that a memory cell array 300 of the non-volatile semiconductor memory can be divided into each column of the prescribed numbers, the memory is made a page register 310 having capacity corresponding to a whole column address of a memory cell array, and the memory has a mask generating section 320 masking an unspecified part at the time of programming when page size is specified. Inputted command decoded by a command decoder 230, the decoded result is given to a control circuit 200, further a column decoder 130, a pointer 330, a row decoder 160, and a voltage generating circuit 240 are driven by the control circuit 200.</p> |
