Semiconductor memory device capable of memorizing multivalued data |
| abstract |
In a memory cell array, a plurality of memory cells connected to word lines and bit lines are arranged in a matrix. A data storage circuit is connected to the bit lines and stores write data. The data storage circuit includes at least one static latch circuit and a plurality of dynamic latch circuits when setting 2 k threshold voltages (k is a natural number equal to 3 or more) in each memory cell in the memory cell array. A control circuit refreshes data by moving the data in one of the plurality of dynamic latch circuits to the static latch circuit and further moving the data in the static latch circuit to one of the plurality of dynamic latch circuits. |
