摘要： A processor-based device (e.g., a wireless device) may include a processor and a semiconductor nonvolatile memory to directly execute an application (e.g., an execute-in-place application) using an associated database. Within a flash memory, in one embodiment, an executable program may be separately stored in a non-fragmented manner from a resident database that includes program management information for use in an execution that does not involve a random access memory, saving time and resources.

摘要： There exists a tradeoff between the fidelity of data storage and the number of bits stored in a memory cell. The number of bits may be increased per cell when fidelity is less important. The number of bits per cell may be decreased when fidelity is more important. A memory, in some embodiments, may change between storage modes on a cell by cell basis.

摘要： A nonvolatile memory device generates a signature using a private key and contents within the memory device. The signature is stored in a secure area within the nonvolatile memory device. A processor having the same private key also generates a signature that is stored in the clear. The processor validates the contents of the nonvolatile memory by comparing the signatures.

摘要： 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.

摘要： 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.
摘要翻译：本文描述了一种用于在存储器中压缩二进制图像并响应于请求对部分存储器进行解压缩的方法和装置，而不使用压缩索引表来找到重新定位的压缩代码。二进制图像在窗口中遍历。每个选择的窗口被压缩以形成具有压缩部分和可用存储器部分的压缩窗口。静态数据在可用存储器部分中回填以实现有效的压缩。在接收到特定物理地址的请求时，由于压缩代码部分未从其原始物理位置重新定位，所以该物理位置的压缩部分被解压缩并被提供用于执行而不使用压缩索引表。

摘要： A code object and flash memory may be updated by storing a new code object in the flash memory. Then, a pointer from a page table may be redirected to point to the new code object. The old code object may then be deleted. As a result, code can be updated without the need for rebooting by using the memory management unit and its page table capability.
摘要翻译：可以通过将新的代码对象存储在闪存中来更新代码对象和闪存。然后，可以将来自页表的指针重定向以指向新的代码对象。然后可以删除旧的代码对象。因此，可以更新代码，而无需通过使用内存管理单元及其页表功能重新启动。
