Patent number: 11901019Abstract: For a non-volatile memory that uses hard bit and soft bit data in error correction operations, to reduce the amount of soft bit data that needs to be transferred from a memory to the controller and improve memory system performance, the soft bit data can be compressed before transfer.

The compressed soft bit data can then be transferred to the transfer data latches of a cache buffer, where the compressed soft bit data can be consolidated and transferred out over an input-output interface. Within the input-output interface, the compressed data can be reshuffled to put into logical user data order if needed.Type: GrantFiled: February 8, 2022Date of Patent: February 13, 2024Assignee: SanDisk Technologies LLCInventors: Hua-Ling Cynthia Hsu, Masaaki Higashitani, YenLung Li, Chen Chen

Patent number: 11894068Abstract: A non-volatile memory combines a hard bit and a soft bit read into a single, efficient soft sense sequence by using two sense per state level to improve read time efficiency. Rather than a standard hard bit read, where two soft bit reads are performed, offset above and below the hard bit read value, the hard bit read is shifted so that it reliable senses one state but less reliably senses the other state and soft bit data is only determined for the less reliably sensed state. This reduces the amount of soft bit data. The efficient soft sense sequence can be used as a default read mode, providing soft bit information for ECC correction without triggering a read error handling flow. Merging the soft bit and hard bit sense into one sequence can avoid extra overhead for read sequence operations.Type: GrantFiled: December 21, 2021Date of Patent: February 6, 2024Assignee: SanDisk Technologies LLCInventor: Hua-Ling Cynthia Hsu

Patent number: 11843921Abstract: Embodiments described herein generally relate to analyzing a signal generated by a device under test (DUT). In particular, the signal generated by the DUT may be compared to a reference signal to determine pass/fail results for the DUT. For example, a method may include: storing, on a computing device, a reference signal from a reference device; receiving a test signal from a device under test (DUT); synchronizing the reference signal and the test signal based on a time-synchronization buffer of each signal; after the synchronization, comparing the test signal and the reference signal to determine a pass or fail result for the DUT; and generating a notification indicating the pass or fail result for the DUT.Type: GrantFiled: August 23, 2021Date of Patent: December 12, 2023Assignee: ROKU, INC.Inventors: Nermin Osmanovic, Deepak Chand Jangid

Patent number: 11842782Abstract: Phased parameterized combinatoric testing for a data storage system is disclosed. A testing recipe can be performed according to different input arguments. Combinatoric testing of the data storage system can be based on different combinations of operations and arguments. The disclosed testing can employ a consistent integer index for arguments passed into the sequenced operations of the recipe. The recipe can be employed to generate a phased test tree that can enable testing based on a phase rather than loading an entire test suite into memory. The consistent integer index can be used to identify failed test cases such that the entire test can be reconstituted from stored failed test information. Distribution of test cases to worker process can based on the phased test tree to facilitate interning an operation. Stored failed test information can include human-readable failure information.Type: GrantFiled: September 30, 2021Date of Patent: December 12, 2023Assignee: EMC IP HOLDING COMPANY LLCInventor: Matthew Bryan

Patent number: 11841790Abstract: Adaptive automated testing methods and systems are disclosed. In an embodiment, an automatic test controller of an automated test system may collect a log of a plurality of actions executed by a plurality of devices of the automated test system and apply a heuristic to the log as the automated test system operates to determine whether to execute a next action by a device of the automated test system. When the next action is to be executed, the automatic test controller automatically directs the device to execute the next action. Otherwise, the automatic test controller indicates the next action was intentionally skipped by recording such omission in the log and automatically skipping the next action.Type: GrantFiled: December 1, 2020Date of Patent: December 12, 2023Assignee: T-Mobile USA, Inc.Inventors: Michael Mitchell, Peter Myron
