Abstract
A non-volatile memory system is provided with a control device and non-volatile memory devices, each including memory cells and data latches. The control device supplies commands to the non-volatile memory devices, including a write command, and first and second read commands. When the control device supplies the write command with write address information and data for storing in the non-volatile memory device, it stores the data to the data latches and then to the memory cells, and then verifies storage. When the control device supplies the first read command with read address information, the nonvolatile memory device reads data stored in the memory cells to the data latches and then outputs the data in the data latches to the control device. When the control device supplies the second read command, the non-volatile memory device outputs data in the data latches to the control device.
