Abstract

In some embodiments, a method for controlling a cache having a volatile memory and a non-volatile memory during a power up sequence is provided. The method includes receiving, at a controller configured to control the cache and a storage device associated with the cache, a signal indicating whether the non-volatile memory includes dirty data copied from the volatile memory to the non-volatile memory during a power down sequence, the dirty data including data that has not been stored in the storage device. In response to the received signal, the dirty data is restored from the non-volatile memory to the volatile memory, and flushed from the volatile memory to the storage device.
