Abstract:
Some of the embodiments of the present disclosure provide a method for programming a flash memory having a plurality of memory blocks, wherein each memory block of the plurality of memory blocks is either a single-level cell (SLC) memory block or a multi-level cell (MLC) memory block, the method comprising assigning a weighting factor to each memory block of the plurality of memory blocks based on whether the memory block is an SLC memory block or an MLC memory block, tracking a number of write—erase cycles for each memory block, and selecting one or more memory blocks for writing data based at least in part on the weighting factor and the tracked number of write—erase cycles of each memory block of the plurality of memory blocks. Other embodiments are also described and claimed.
