Abstract:
Reliability of stored data is improved without increasing power consumption in a case where a threshold of a control element in a memory cell changes. In a memory including the memory cell, a reference cell, and an access control unit, the memory cell changes from a non-conduction state to a conduction state according to an applied voltage at a threshold voltage and changes to a high resistance state and a low resistance state according to the voltage applied in the conduction state. The reference cell changes from a non-conduction state to a conduction state at a reference threshold voltage according to an applied voltage. The access control unit estimates that the reference threshold voltage measured in the reference cell is the threshold voltage of the memory cell and applies a voltage to the memory cell when accessing the memory cell.

Claim (Index 10):
The memory according to  claim 9 , wherein, when the access control unit writes in the memory cell connected to a selected row signal line being one of the plurality of row signal lines and a selected column signal line being one of the plurality of column signal lines, the access control unit estimates a threshold voltage of a half-selected row memory cell being the memory cell connected to the selected row signal line and a column signal line other than the selected column signal line and a threshold voltage of a half-selected column memory cell being the memory cell connected to the selected column signal line and a row signal line other than the selected row signal line by the reference threshold voltage and applies a voltage to the half-selected row memory cell and the half-selected column memory cell.
