Abstract
Official abstract text for this publication.
A method and system for booting an electronic device from a NAND flash memory includes a NAND flash controller that receives an event trigger for fetching a pre-boot code stored in the NAND flash memory. Based on the event trigger type, booting parameters are loaded into the controller including a boot frequency of the NAND flash memory. The controller searches for a good memory block in which the pre-boot code is stored by checking the first and second or the first and last pages of a memory block and fetches a portion or the entire pre-boot code based on the event trigger type at the boot frequency.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for fetching a pre-boot code from a NAND flash memory by a NAND flash controller, for booting an electronic device, wherein the NAND flash memory includes a plurality of memory blocks and each memory block includes a plurality of pages, the method comprising: loading a first set of boot parameters into a programming register of the NAND flash controller upon receipt of a boot triggering event; identifying a good memory block in which the pre…
