SYSTEM AND METHOD INCLUDING THREE DIMENSIONAL NONVOLATILE MEMORY DEVICE AND RANDOM ACCESS MEMORY

摘要

A program method for a memory system including a three-dimensional nonvolatile memory having multi-level memory cells and a random access memory. The method uses the random access memory to variously store selected bits of multi-bit data during the programming of a row of memory cells in the three-dimensional nonvolatile memory.

1. A program method for a memory system including a three-dimensional nonvolatile memory having a page buffer and multi-level memory cells arranged along a row direction, and a random access memory, the method comprising:
receiving externally provided program data; determining whether the received program data is whole data associated with the memory cells and corresponding to multi-page data; and upon determining that the received program data is whole data programming the program data by loading the multi-page data to the page buffer and then simultaneously programming the bits of the multi-page data from the page buffer to the memory cells, else storing the received program data in the random access memory.
