Performance enhancement of a storage device using an integrated controller-buffer

Abstract:

Embodiments described herein provide a system for facilitating performance enhancement of a storage device. During operation, the system obtains a write request for storing a data page in the storage device. The system then stores the page in a non-volatile accumulation buffer integrated with the storage device and determines whether the accumulation buffer has accumulated at least one block of data. The block of data can indicate a unit of an erasure operation on the storage device. If the accumulation buffer has accumulated the one block of data, the system transfers the block of data to a first block in the storage device from the accumulation buffer.
