Abstract:
Systems and methods are provided for using a NAND-type non-volatile memory (“NVM”), such as NAND flash memory, to store NV pre-boot information for a bootloader (e.g., a second state bootloader) or an operating system. The NV pre-boot information can include, for example, environment variables storing the configuration or state of an electronic device. In some embodiments, an electronic device including the NAND-type NVM may allocate a portion of the super blocks in the NAND-type NVM to storing the NV pre-boot information. The electronic device may store a redundant copy of the NV pre-boot information into the allocated portion of each IC die of the NAND-type NVM.
