Abstract
A memory system includes a controller and a flash memory including a plurality of first blocks. The controller writes a value having a first number of bits per memory cell to a plurality of second blocks, and writes a value having a second number of bits per memory cell to a plurality of third blocks among the first blocks. The second number is more than the first number. The controller writes data from a host device to the second blocks and transcribes valid data from the second blocks to the third blocks. The controller controls the number of second blocks in the first blocks according to an order of completion of the data writing to one or more third blocks and an amount of valid data stored in each of the one or more third blocks.
