Abstract
A semiconductor storage device is provided with a memory cell array comprising a plurality of word lines including word lines that are adjacent to one another; and a TRR address conversion unit that selects the word line in response to the input of an address signal indicating a first value while in a first operation mode and selects the word line in response to the input of an address signal indicating a first value while in a target row refresh mode. Due to the fact that address conversion is performed on the semiconductor storage device side in the present invention, it is sufficient for a control device to output, for example, the address of a word line having a high access count to the semiconductor storage device during a target row refresh operation. As a result, control of the target row refresh operation on the control device side is facilitated.
