Abstract
A memory device includes a memory cell array and peripheral circuits coupled to the memory cell array. The peripheral circuits are configured to perform twice program operations on one or more first memory cells in the memory cell array for storing cold data into the one or more first memory cells. The twice program operations include a first time program operation and a second time program operation. To perform the twice program operations, the peripheral circuits are configured to performing the first time program operation for successfully storing the cold data into the one or more first memory cells, and performing the second time program operation for improving retention characteristics of the cold data.
