15 Claims

1. A method for performing a write operation, the method comprising:

selecting, by a host, at least a free write buffer from a plurality of write buffers of a shared memory buffer (SMB) by accessing a cache structure within the SMB for tracking the free write buffer;

sending, by the host, at least a logical address accessed from the cache structure with respect to the selected write buffer to issue a write-command to a non-volatile memory;

receiving a locking instruction of the selected write buffer from the non-volatile memory;

updating a status of the selected write buffer within the cache structure based on the received locking instruction; and

providing, to the non-volatile memory, contents of one or more locked write buffers including the selected write buffer.
