DensBits Technologies Assigned Three Patents

Flash memory management, configurable flash interface, dynamic erase, program control for flash memory device memories

Flash memory management
DensBits Technologies Ltd., Haifa, Israel, has been assigned a patent (8,996,790) developed by Segal, Avigdor, Netanya, Israel, Weingarten, Hanan, Herzelia, Israel, and Vainerovitch, Alik, Kiryat Ono, Israel, for a “system and method for flash memory management.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method, a computer readable medium and a system for managing flash memory. The method may include receiving multiple data sectors from an interface, writing the multiple data sectors into a data buffer that is nonvolatile, creating a pointer in a data management structure that is stored in a metadata buffer that is nonvolatile, for each data sector corresponding to a storage location of the data sector in the data buffer, if a predefined condition is reached, merging data sectors stored in the data buffer with data sectors that are already stored in a sequential nonvolatile portion of the flash memory device, wherein the sequential nonvolatile portion differs from the data buffer.

The patent application was filed on March 29, 2012 (13/434,083).

Configurable flash interface
DensBits Technologies Ltd., Haifa, Israel
, has been assigned a patent (8,996,788) developed by Nassie, Amir, Haifa, Israel, for a “configurable flash interface.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A flash memory controller, a non-transitory computer readable medium and a method for performing operations with a flash memory device, the method may include receiving, by a flash memory controller, a request to perform a requested operation with the flash memory device, selecting multiple selected instructions to be executed by a programmable module of the flash memory controller, based upon, a) an interface specification supported by the flash memory device and, b) the requested operation, wherein the programmable module comprising multiple operation phase circuits, and executing the multiple selected instructions by the programmable module, wherein the executing of the multiple selected instructions comprises executing a plurality of selected instructions by multiple operation phase circuits, wherein different operation phase circuits are arranged to execute different operation phases of the requested operation.

The patent application was filed on February 9, 2012 (13/370,114).

Dynamic erase and program control for flash memory device memories
DensBits Technologies Ltd., Haifa, Israel
, has been assigned a patent (8,995,197) developed by Steiner, Avi, Kiryat Motzkin, Israel, and Weingarten, Hanan, Herzelia, Israel, for a “system and methods for dynamic erase and program control for flash memory device memories.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A computer readable medium, a system and a method for flash memory device parameter optimization, the method may include: receiving or generating an estimate of a wear level of at least one group of flash memory cells of the flash memory device, and finding erase parameters and programming parameters to be applied on one or more groups of flash memory cells of the flash memory device in response to estimate of the wear level.

The patent application was filed on August 27, 2012 (13/595,782).
