Non-volatile memory system including a control device to control writing, reading and storage and output operations of non-volatile devices including memory cells and data latches

A nonvolatile memory system comprising:

• a control device;
• and
• a plurality of nonvolatile memory devices each of which has a plurality of memory cells and a plurality of data latches;
• wherein said control device supplies a plurality of commands to said nonvolatile memory devices, which commands comprise a write command, a first read command and a second read command,
• wherein, when said control device supplies said write command with write address information and data for storing in said nonvolatile memory device, said nonvolatile memory device stores data to said data latches, stores said data in said data latches to ones of said memory cells and verifies whether said write data has been stored in said memory cells or not,
• wherein, when said control device supplies said first read command with read address information, said nonvolatile memory device reads data stored in ones of said memory cells to said data latches and outputs said data in said data latches to said control device, and
• wherein, when said control device supplies said second read command, said nonvolatile memory device outputs data in said data latches to said control device.
