20150261797 | SYSTEM AND METHOD FOR MANAGEMENT OF GARBAGE COLLECTION OPERATION IN A SOLID STATE DRIVE - A method of garbage collection in a storage device including a central processing unit (CPU), a self-organized fast release buffer (FRB), and a non-volatile memory, the method including receiving a command to perform garbage collection in a first block stripe of the non-volatile memory from the CPU, the command including a second block stripe to write to and valid logical block numbers (LBNs) corresponding to a first codewords (CWs) stored in the first block stripe, allocating space in a buffer memory of the FRB for storage of the first CWs, storing the first CWs into the allocated space in the buffer memory, transferring a second CWs to a plurality of physical addresses in the second block stripe of the non-volatile memory, and sending the valid LBNs and the plurality of physical addresses to the CPU to update a logical-to-physical table, wherein the second CWs is based on the first CWs. | 09-17-2015 |
20150261475 | PROGRAMMABLE DATA READ MANAGEMENT SYSTEM AND METHOD FOR OPERATING THE SAME IN A SOLID STATE DRIVE - A method of reading host data from a storage device including a central processing unit (CPU), a self-organized fast release buffer (FRB), and a non-volatile memory, the storage device being in communication with a host, the method including receiving, by the FRB, a command to read host data stored in the non-volatile memory from the CPU, the host data being stored in the non-volatile memory as one or more codewords (CWs), allocating space, by the FRB, in a buffer memory of the FRB for storage of the one or more CWs, storing, by the FRB, the one or more CWs into the allocated space in the buffer memory, extracting, by the FRB, the host data from the stored one or more CWs, and transferring, by the FRB, the host data to the host. | 09-17-2015 |
20150261456 | CONFIGURABLE READ-MODIFY-WRITE ENGINE AND METHOD FOR OPERATING THE SAME IN A SOLID STATE DRIVE - A method of writing host data to a storage device including a central processing unit (CPU), a self-organized fast release buffer (FRB), and a non-volatile memory, the storage device being in communication with a host, the method including receiving a command from the CPU to write the host data to a location in the non-volatile memory, the host data being associated with a first plurality of codewords (CWs), allocating space in a buffer memory of the FRB for storage of the first CWs, storing the first CWs into the allocated space in the buffer memory, extracting data from the stored first CWs, organizing the extracted data and the host data into a second plurality of CWs, transferring a second CWs to a physical addresses in the non-volatile memory, and sending the plurality of physical addresses to the CPU to update a logical-to-physical table. | 09-17-2015 |
20150149697 | SYSTEM AND METHOD FOR SUPPORTING ATOMIC WRITES IN A FLASH TRANSLATION LAYER - A method of maintaining and updating a logical-to-physical (LtoP) table in a storage device including a processor, a volatile memory, and a non-volatile memory, the storage device being in communication with a host utilizing atomic writes, the method including receiving, by the processor, data for storing at a plurality of physical addresses in the non-volatile memory, the data being associated with a plurality of logical addresses of the host, storing, by the processor, the plurality of physical addresses in an atomic segment in the volatile memory, storing, by the processor, one or more of zones of the LtoP table in the non-volatile memory, the one or more zones of the LtoP table corresponding in size to the atomic segment, and updating the one or more zones of the LtoP table with the plurality of physical addresses in the atomic segment. | 05-28-2015 |
20150032938 | SYSTEM AND METHOD FOR PERFORMING EFFICIENT PROCESSING OF DATA STORED IN A STORAGE NODE - A system and method of providing enhanced data processing and analysis in a storage device, such as a solid state drive (SSD). The SSD includes flash memory and an SSD processing unit capable of executing searches on the data in the flash memory without returning all of the data to be searched to a host CPU outside of the SSD. Other processing capabilities incorporated into the SSD may include encryption and decryption, compression and decompression, and in-line indexing of data. | 01-29-2015 |
20150032937 | SYSTEM AND METHOD FOR PERFORMING EFFICIENT SEARCHES AND QUERIES IN A STORAGE NODE - A system and method of providing enhanced data processing and analysis in a storage node, such as a solid state drive (SSD). The SSD includes flash memory and an SSD processing unit capable of executing searches and analysis on the data in the flash memory without returning all of the data to be searched to a host CPU outside of the SSD. Other processing capabilities incorporated into the SSD may include encryption and decryption, compression and decompression, and in-line indexing of data, and data analytics. | 01-29-2015 |
