    • Aspects of the subject matter described herein relate to storage systems and aliased memory. In aspects, a file system driver or other component may send a request to a memory controller to create an alias between two blocks of memory. One of the blocks of memory may be used for main memory while the other of the blocks of memory may be used for a storage system. In response, the memory controller may create an alias between the blocks of memory. Until the alias is severed, when the memory controller receives a request for data from the block in main memory, the memory controller may respond with data from the memory block used for the storage system. The memory controller may also implement other actions as described herein.

    • The present idea provides a high read and write performance from/to a solid state memory device. The main memory (31) of the controller (1) is not blocked by a complete address mapping table covering the entire memory device (2). Instead such table is stored in the memory device (2) itself, and only selected portions of address mapping information are buffered in the main memory (31) in a read cache (311) and a write cache (312). A separation of the read cache (311) from the write cache (312) enables an address mapping entry being evictable from the read cache (311) without the need to update the related flash memory page storing such entry in the flash memory device (2). By this design, the read cache (311) may advantageously be stored on a DRAM even without power down protection, while the write cache (312) may preferably be implemented in nonvolatile or other fail-safe memory. This leads to a reduction of the overall provisioning of nonvolatile or fail-safe memory and to an improved scalability and performance.
    • 目前的想法提供了对固态存储器设备的高读写性能。 控制器(1)的主存储器(31)不被覆盖整个存储器设备(2)的完整地址映射表阻塞。 相反,这样的表被存储在存储器设备(2)本身中,并且只有地址映射信息的所选部分被缓存在读取高速缓存(311)和写入高速缓存(312)中的主存储器(31)中。 读取高速缓存(311)与写入高速缓存(312)的分离使得地址映射条目能够从读取高速缓存(311)中逐出,而不需要更新在闪存器件(2)中存储这样的条目的相关的闪存页面 )。 通过这种设计,即使没有断电保护,读取高速缓存(311)也可以有利地存储在DRAM上,而写入高速缓存(312)可以优选地在非易失性或其他故障安全存储器中实现。 这导致非易失性存储器或故障安全存储器的整体配置减少并且可扩展性和性能得到改善。
