Abstract
A number of read cycles applied to a selected memory location of a memory device, such as a variable-resistance memory device, is monitored. Write data to be written to the selected memory location is received. Selective pre-write verifying and writing of the received write data to the selected memory location occurs based on the monitored number of read cycles. Selectively pre-write verifying and writing of the received write data may include, for example, writing received write data to the selected memory cell region without pre-write verification responsive to the monitored number of read cycles being greater than a predetermined number of read cycles.
