Efficient data path architecture for flash devices configured to perform multi-pass programming

摘要

Efficient data path architecture for flash devices requiring multi-pass programming utilizes an external memory as an intermediate buffer to store the encoded data used for a first pass programming of the flash device. The stored encoded data can be read from the external memory for subsequent passes programming instead of fetching the data from an on-chip memory, which stores the data received from a host system. Thus, the on-chip memory can be made available to speed up the next data transfer from the host system.
