Abstract
Methods, devices, and systems for managing data refresh for semiconductor devices are provided. In one aspect, a semiconductor device includes a memory cell array having a plurality of blocks each including multiple pages and one or more integrated circuits coupled to the memory cell array. The one or more integrated circuits are configured to: read specific data from a page of a block in the memory cell array, perform a logic operation on the specific data in the page to obtain a logic operation result, count a number of bits having a specific value among the logic operation result, determine whether the number of bits is within a data refresh criterion for the page, and in response to determining that the number of bits is outside of the data refresh criterion, generate a data refresh warning message for the page in the block.
