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 12):
An information processing system comprising:\n a memory including: a memory cell which 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 a voltage applied in the conduction state; a reference cell including a reference element which changes from a non-conduction state to a conduction state according to an applied voltage at a reference threshold voltage; and an access control unit which estimates the reference threshold voltage measured in the reference cell to be the threshold voltage of the memory cell and applies a voltage to the memory cell at a time of access to the memory cell; and a host computer which accesses to the memory.
