2.6.2 External (BufferRAM) Memory Organization

The on-chip external memory is comprised of 3 buffers used for Boot Code storage and data buffering.

The BootRAM is a 1KB buffer that receives Boot Code from the internal memory and makes it available to the host at start up.

There are two independent 2KB bi-directional data buffers, DataRAM0 and DataRAM1. These dual buffers enable the host to execute simul- taneous Read-While load, and Write-While-program operations after Boot Up. During Boot Up, the BootRam is used by the host to initialize the main memory, and deliver boot code from NAND Flash core to host.

The external memory is divided into a main area and a spare area. Each buffer is the equivalent size of a Sector. The main area data is 512B. The spare area data is 16B.
