Abstract
A memory system includes a memory device including first memory blocks each including a memory cell storing a 1-bit data, and second memory blocks each including a memory cell storing a multi-bit data. The memory system further includes a controller configured to estimate data input/output speed of an operation requested by an external device and to determine, based on the estimated data input/output speed, a buffering ratio of pieces of buffered data, temporarily stored in the first memory blocks, to pieces of inputted data. The controller uses the buffer ratio to determine whether to program pieces of inputted data into the second memory blocks directly or to buffer the inputted data in the first memory blocks before programming it into the second memory blocks.
