2.0 DEVICE DESCRIPTION
2.1 Detailed Product Description
The MuxOneNAND is an advanced generation, high-performance NAND-based Flash memory.
It integrates on-chip a single-level-cell (SLC) 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 Bufferand NAND Flash Array.
Clock speeds up to 66MHz / 83MHz with a x16 wide I/O yields a 108MByte/second bandwidth.
The 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.
