  • Patent number: 11837277
    Abstract: The present disclosure generally relates to improved foggy-fine programming. Rather than initially writing to SLC and then later performing a foggy write to QLC with the data read from SLC and then a fine write to QLC with data re-read from SLC, the foggy write to QLC can be performed in parallel to the initial writing to SLC using the same buffer. Once the foggy write to QLC has completed, and the writing to SLC has also completed, the data buffer can be released. The data written in SLC is then be read from SLC and passes through a relocation buffer for the first and only time to then be written using fine programming to QLC. Thus, the data only passes through the relocation buffer one time and the relocation buffer can be freed to usage after only one pass of the data therethrough.

  • Patent number: 11756638
    Abstract: Disclosed in some examples are methods, systems, memory devices, machine readable mediums configured to intentionally degrade NAND performance when a value of a NAND health metric indicates a potential for failure to encourage users to replace or backup their devices before data loss occurs. For example, the system may track a NAND health metric and when that metric reaches a predetermined threshold or state, the system may intentionally degrade performance. This performance degradation may be more effective than a warning to effect device backup or replacement.

  • Patent number: 11715514
    Abstract: A bit cell of an SRAM implemented using standard cell design rules includes a write portion and a read portion. The write portion includes a pass gate coupled to an input node of the bit cell and supplies data on the input node to a first node of the bit cell while write word line signals are asserted. An inverter is coupled to the first node and supplies inverted data. A keeper circuit that is coupled to the inverter maintains the data on the first node when the write word line signals are deasserted. The read portion of the bit cell receives read word line signals and the inverted data and is responsive to assertion of the read word line signals to supply an output node of the read portion of the bit cell with output data that corresponds to the data on the first node.

  • Patent number: 11676671
    Abstract: An amplification-based read disturb information determination system includes a storage device coupled to a global read temperature identification system. The storage device amplifies data errors in a first row in its storage subsystem by shifting a first value voltage reference level associated with the first row to provide a second value voltage reference level, reads data stored in bits provided in the first row and error correction information associated with the data, and uses the error correction information to identify a number of the bits that store portions of the data with errors. For the first row and based on the number of bits that store portions of the data with errors, the storage device determines read disturb information and uses it to generate a read temperature for a second row in its storage subsystem that it provides to the global read temperature identification system.
