Abstract: Provided are a method, device, and system for booting from a memory device having an array of blocks of cells. An initial memory map has a mapping of memory addresses to accessible blocks of cells in the memory device that are accessible following a boot sequence. There are secure blocks of cells in addition to the accessible blocks of cells that are not accessible through the memory addresses in the initial memory map. In response to detecting an initialization event, the secure blocks of cells are mapped to a range of memory addresses in the memory map to generate an altered memory map. Code is executed in the secure blocks using the range of memory addresses in the altered memory map. The range of memory addresses mapping to the secure blocks are remapped to map to the accessible blocks to which the range of memory addresses mapped in the initial memory map to restore the initial memory map from the altered memory map.

Abstract: An embodiment of the present invention provides an apparatus, comprising flash memory capable of blocking reads from a secure boot block and capable of disabling authenticated operations after a secure boot process. A configuration register may control access to the secure boot block and enable/disable the authenticated operations. An embodiment of the present invention provides that a secure NOR flash technology may utilize a resident micro-controller to perform authenticated write operations to the NOR flash. The configuration register may be reset after a hard boot thereby enabling authenticated operations and read access of the secure boot block and may be capable of being set to disable authenticated operations and read access of the secure boot block.

Abstract: Apparatus and systems, as well as methods and articles, may operate to receive a disable command from a remote network location to disable a plurality of memory read operations associated with a networked device, authenticate the remote network location using a controller associated with the networked device, and disable the plurality of memory read operations using the controller. Receipt of an enable command may re-enable memory read operations after confidence in the device has been restored.

Abstract: Remediation code may be stored in an area of a flash memory which is inaccessible to normal write commands. When a command is received that is directed to a block of a flash array which has a certain bit set, that block can be recognized as one which relates to the remediation code in one embodiment. In such case, the request may be coalesced with other requests in a remediation memory. When sufficient number of such operations have been coalesced, they may be authenticated in some embodiments.

Abstract: A method and apparatus is described herein for compressing a binary image in memory and decompressing a portion memory in response to a request, without using a compression index table to find relocated compressed code. A binary image is traversed in windows. Each selected window is compressed to form compressed windows having a compressed portion and an available memory portion. Static data is backfilled in available memory portions to achieve efficient compression. Upon receiving a request to a specific physical address, the compressed portion of that physical location is decompressed and provided for execution without using a compression index table, as the compressed code portion was not relocated from its original physical location.

Abstract: Code objects stored in faster and slower memory may be checked to determine their access frequency. For example, in connection with a paging system, a reference count may be accessible. Based on the reference count and other statistics, code objects that are more frequently accessed may be moved to faster memories, such as faster flash memories, and code objects that are less frequently accessed may be moved to slower memories. In some embodiments, this will increase the access speed of the data in the system as a whole.
