摘要：
A volatile or nonvolatile cache memory can cache mass storage device read data and write data. The cache memory may become inaccessible, and I/O operations may go directly to the mass storage device, bypassing the cache memory. A log of write operations may be maintained to update the cache memory when it becomes available.
