Abstract: A memory system includes a firmware unit and a cache module that includes a cache controller and a cache memory. The cache controller receives an I/O message that includes a local message ID (LMID) and data to be written to a logical drive (LD), stores the data in a cache segment (CS) row of the cache memory and sends an ID of the CS row to the firmware unit. The firmware unit, in response to receiving the ID of the CS row, acquires a timestamp and stores the timestamp to check against a cache flush timeout for the CS row. The firmware unit periodically checks cache flush timeout and in response to detecting the cache flush timeout, sends a flush command with the ID of the CS row to the cache controller. The cache controller, in response to receiving the flush command, flushes the first data of the CS row.
