2.0 DEVICE DESCRIPTION

2.1 Detailed Product Description

The Flex-MuxOneNAND is an advanced generation, high-performance MLC NAND-based Flash memory(Which can be programmed as both

SLC and MLC).

It integrates on-chip a convertible(SLC and MLC) NAND Flash Array memory with two independent data buffers, boot RAM buffer, a page

buffer for the Flash array, and a one-time-programmable block.

The combination of these memory areas enable high-speed pipelining of reads from host, BufferRAM, Page Buffer, and NAND Flash Array.

Clock speeds up to 66MHz / 83MHz with a x16 wide I/O yields a 83MByte/second in SLC and 71MByte/second in MLC read bandwidth

The Flex-MuxOneNAND also includes a Boot RAM and boot loader. This enables the device to efficiently load boot code at device startup

from the NAND Array without the need for off-chip boot device.

One block of the NAND Array is set aside as an OTP memory area, and 1st Block (Block 0) can be used as OTP area. This area, available to

the user, can be configured and locked with secured user information.

On-chip controller interfaces enable the device to operate in systems without NAND Host controllers.
