Facebook Assigned Patent

Facebook, Inc., Menlo Park, CA, has been assigned a patent (9,377,958) developed by Vijayrao, Narsing, Santa Clara, CA, Jia, Hongzhong, Cupertino, CA, and Taylor, Jason, Berkeley, CA, for a “allocation of read/write channels for storage devices.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Channel performance can be improved in a storage device, such as a flash memory or a flash-based SSD, by dynamically provisioning available data channels for both write and read operations. In one aspect, a set of available data channels on a storage device is partitioned into a set of write channels and a set of read channels according to a read-to-write ratio. Next, when an incoming data stream of mixed read requests and write requests arrives at the storage device, the allocated read channels process the read requests on a first group of memory blocks, which does not include garbage collection and write amplification on the first group of memory blocks. In parallel, the allocated write channels process the write requests on a second group of memory blocks, which does include garbage collection and write amplification on the second group of memory blocks.“

The patent application was filed on August 12, 2014 (14/457,864).
