ST-Ericsson (STMicroelectronics) Assigned Patent

ST-Ericsson SA, (merged with STMicroelectronics), Plan-les-Ouates, Switzerland, has been assigned a patent (9,183,128) developed by Das Purkayastha, Saugata, Bangalore, India, for a “device controller for a memory device.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”The invention provides a method for controlling writing of data to a data storage card having a device controller and a storage medium. Particularly, the device controller receives a meta data synchronization disable command and in response, enters a first mode. In the first mode, the device controller does not synchronize meta data related to a data write request to write the data to the storage medium, leaving corresponding unsynchronized meta data. The device controller receives a data write request to write the data, and in response, effects the data write request such that the data is written to the storage medium. However, the meta data related to the data write request is not synchronized to the storage medium. Other aspects provide a corresponding device controller and software/firmware.“

The patent application was filed on February 23, 2012 (13/977,623).
