Abstract
A page data (e.g., upper page data) received from a host is stored in a transfer buffer of a controller of a solid state drive. Another page data (e.g., lower page data) is read from a non-volatile memory (e.g., a NAND memory) to store in the transfer buffer as an error corrected page data. The error corrected page data and the page data are written to the non-volatile memory. In additional embodiments, a controller loads a page data (e.g., upper page data) received from the host in one or more NAND page buffers. The controller reads another page data (e.g., lower page data) from a NAND memory to store in a transfer buffer as an error corrected page data. The error corrected page data stored in the transfer buffer is loaded to the one or more NAND page buffers.
