Abstract
A selection module selects memory blocks of a flash memory in response to (i) the memory blocks being partially written with first data and (ii) receiving a write command to write second data to the memory blocks. A control module, prior to erasing the first data from the memory blocks, collects the first data and writes the collected data in a portion of a dynamic random access memory instead of writing the collected data in the flash memory. A location description module generates a description table indicating whether data in memory locations in the portion of the dynamic random access memory are valid or invalid. A rate of adding data to the portion becomes equal to a rate at which data in memory locations in the portion becomes invalid so that the collected data is written in the portion without first merging the collected data.
