METHOD AND APPARATUS FOR PARTIAL PAGE COMPRESSION

摘要

A memory system includes a memory device, the memory device including, a memory cell array, and a compression encoder, the memory cell array including a first plurality of multi level cells (MLCs), the memory device being configured to, generate a first partial page by performing one or more first sensing operation on the first plurality of MLCs using one or more first reference voltages, output the first partial page, generate a second partial page by performing a second sensing operation on the first plurality of MLCs based on a second reference voltage, the second reference voltage having a different voltage level than the one or more first reference voltages, generate a second compressed partial page by compressing the second partial page using the compression encoder, and output the compressed second partial page.
