MEMORY SYSTEM AND DRIVING METHOD THEREOF

摘要

A memory system including an ONENAND and NAND flash memory and a driving method thereof are provided to reduce the load of a host processor within a memory system by controlling a plurality of memory devices by using a microcode. A host processor(10) produces a micro code. The micro code is a plurality of instructions controlling a memory within first and second memory devices inside the memory system. A DMA(50) transmits the micro code to a top control sequencer(20) and A channel department B channel control sequencer through the system bus(60). The micro code transmitted by DMA is stored in the sequencer internal memory. The micro code stored in the sequencer internal memory is performed.
