The OneNAND 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
Clock speeds up to 54MHz with a x16 wide I/O yields a 68MByte/second bandwidth.
The OneNAND 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. 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.
