Abstract: Provided are a storage device, system, and method for throttling host writes in a host buffer to a storage device. The storage device is coupled to a host system having a host buffer that includes reads and writes to pages of the storage device. Garbage collection consolidates valid data from pages in the storage device to fewer pages. A determination is made as to whether a processing measurement at the storage device satisfies a threshold. A timer value is set to a positive value in response to determining that the processing measurement satisfies the threshold. The timer is started to run for the timer value. Writes from the host buffer are blocked while the timer is running. Writes remain in the host buffer while the timer is running. A write is accepted from the host buffer to process in response to expiration of the timer.

Abstract: Threshold voltage shift values, or TVS values, are calibrated for a non-volatile memory unit including strings of memory cells organized into memory pages, the memory pages being organized into blocks. The calibration involves a read operation to read a given page of the memory pages, based on given one or more TVS values for the given page. In response to a read failure of the read operation, the calibration determines one or more corrected TVS values based on one or more reference TVS values of one or more reference pages of the memory pages. The calibration subsequently performs a read operation to read the given page based on the one or more corrected TVS values. This calibration exploits TVS values of reference pages to determine corrected TVS values of the failing page, instead of finding appropriate TVS values by repeatedly re-reading the failing page.

Abstract: A non-volatile memory includes a plurality of cells each individually capable of storing multiple bits of data including bits of multiple physical pages. A controller of the non-volatile memory issues a command to perform a programming pass for a physical page among the multiple physical pages. The controller determines whether or not the programming pass took less than a minimum threshold time and no program fail status indication was received. Based on determining the programming pass took less than a minimum threshold time and no program fail status indication was received, the controller detects an under-programming error and performs mitigation for the detected under-programming error.

Abstract: A controller of a non-volatile memory detects errors in data read from a particular physical page of the non-volatile memory. Based on detecting the errors, the controller performs a read voltage threshold calibration for a page group including the particular physical page and a multiple other physical pages. Performing the read voltage threshold calibration includes calibrating read voltage thresholds based on only the particular physical page of the page group. After the controller performs the read voltage threshold calibration, the controller optionally validates the calibration. Validating the calibration includes determining whether bit error rates diverge within the page group and, if so, mitigating the divergence. Mitigating the divergence includes relocating data from the page group to another block of the non-volatile memory.

Abstract: Secure access recovery to a network device includes encrypting a user password into an encrypted target password using a secret regenerative key, and adding a one-time password seed and the encrypted target password into a secure recovery container, which is stored securely in the network device and a trusted recovery device. In response to a recovery request, a one-time password can be generated using the one-time password seed to retrieve the encrypted target password from the recovery device. A decrypted recovery password is generated based on executing decryption on an input string based on the secret regenerative key. The encrypted target password, retrieved from the secure recovery container in the network device, is decrypted into a decrypted target password based on the secret regenerative key. Secure access is recovered in response to determining the decrypted recovery password matches at least a part of the decrypted target password.

Abstract: A non-volatile memory includes a plurality of physical blocks each including a respective plurality of cells, where each cell is individually capable of storing multiple bits of data. A controller for the non-volatile memory maintains dynamically resizable pools of physical blocks, including at least a low-density pool of physical blocks in which cells are configured to store a fewer number of bits and a high-density pool of physical blocks in which cells are configured to store a greater number of bits. The controller detects an imbalance in utilization between the low-density and high-density pools and, based on detection of the pool imbalance, restricts data placement in the low-density pool, enables garbage collection from the low-density pool back into the low-density pool to compact the low-density pool, and re-enables data placement to the low-density pool based on availability of a threshold number of free physical blocks in the low-density pool.

Abstract: A computer-implemented method, according to one embodiment, includes: maintaining a first subset of the plurality of blocks in a first pool, where the blocks maintained in the first pool are configured in SLC mode. A second subset of the plurality of blocks is maintained in a second pool, where the blocks maintained in the second pool are configured in multi-bit-per-cell mode. A current I/O rate for the memory is identified during runtime, and a determination is made as to whether the current I/O rate is outside a first range. In response to determining that the current I/O rate is not outside the first range, the blocks maintained in the first pool are used to satisfy incoming host writes. Moreover, in response to determining that the current I/O rate is outside the first range, the blocks maintained in the second pool are used to satisfy incoming host writes.
