Classification: CPC G | IPC G

Claim 15:
16. The method as set forth in claim 15, wherein the memory apparatus further includes a read timer configured to determine a read time span of each of the plurality of read operations of each of the plurality of blocks of the memory cells, the read frequency metric is a calculated read frequency based on the read time span and the block read quantity, the method further includes the steps of:
determining and recording a current time stamp;
initializing the block read quantity associated with the one of the plurality of blocks as zero following recording of the current time stamp;
determining and recording a new time stamp in response to the block read quantity being greater than the block read quantity threshold;
calculating the calculated read frequency equal to the block read quantify divided by the read time span, the read time span being equal to the new time stamp minus the current time stamp;
determining whether the calculated read frequency is greater than a read frequency threshold;
concluding the memory apparatus is ready for the next read and returning to receiving the read request associated with one of the plurality of read operations in response to the calculated read frequency not being greater than the read frequency threshold; and
relocating the data of the one of the plurality of blocks in response to the calculated read frequency being greater than the read frequency threshold.
