The present invention relates to a single-board processor card configured for use in a 1U CubeSat payload form-factor multi-purpose architecture, including: a field-programmable-gate-array (FPGA) which is reconfigurable in flight; wherein a configuration memory of the FPGA can be scrubbed in flight to correct errors or upsets; and a radiation-hardened monitor (RHM) which provides radiation mitigation and system monitoring of the single-board processor card, and which reconfigures said FPGA during flight, scrubs the configuration memory, and monitors a health of the FPGA. The 1U CubeSat payload form-factor multi-purpose architecture includes a backplane having a plurality of slots, one of the plurality of slots which accommodates the single-board processor card, wherein the backplane routes signals to a plurality of standard-sized processor cards, interchangeably disposed in any of the plurality of slots.

A semiconductor memory device includes a memory cell array, an ECC engine, a voltage generator and a control logic circuit. The memory cell array includes a plurality of memory cells coupled to word-lines and bit-lines, and a plurality of sense amplifiers to sense data stored in the plurality of memory cells. The ECC engine reads memory data from a target page of the memory cell array, performs an ECC decoding on the memory data, detects, based on the ECC decoding, an error in the memory data, and outputs error information associated with the error. The voltage generator provides driving voltages to the plurality of sense amplifiers, respectively. The control logic circuit controls the ECC engine, and controls the at least one voltage generator to increase an operating margin of each of the plurality of sense amplifiers based on error pattern information including the error information.

A memory device is set to a performance mode. Data item is received. The data item in a page of a logical unit of the memory device associated with a fault tolerant stripe is stored. A redundancy metadata update for the fault tolerant stripe is delayed until a subsequent media management operation.

A system is provided to receive a request to write data to a storage device, wherein the data is associated with a file name and a file path. The system performs a hash function on an input based on the file name and the file path to obtain a hash value, wherein the hash function comprises a plurality of hash methods performed on the input. The system maps the hash value to a physical location in the storage device, and writes the data to the physical location in the storage device.

Methods, devices, and systems related to memory device on-die ECC data are described. In an example, a scrub operation can be performed on data in order to determine which rows of memory cells in an array include a particular number of errors. The particular number of errors can be a number of errors that exceed a threshold number of errors. An address of the determined rows with the particular number of errors can be stored in memory cells of the array for later access. The address of the determined rows can be accessed to perform a user-initiated repair operation, a self-repair operation, a refresh operation, and/or to alter timing of access of the cells or alter voltage of the cells.

A computer-implemented method includes fetching, by a controller, data using a plurality of memory channels of a memory system. The method further includes detecting, by the controller, that a first memory channel of the plurality of memory channels has not returned data. The method further includes marking, by the controller, the first memory channel from the plurality of memory channels as unavailable. The method further includes, in response to a fetch, reconstructing, by the controller, fetch data based on data received from all memory channels other than the first memory channel.

A method of managing errors in a plurality of storage drives includes receiving, at a memory controller coupled to at least one storage medium in an SSD, a read command from a host interface. The method also includes retrieving, from the storage medium, read data corresponding to a plurality of data chunks to be retrieved in response to the read command, and determining that at least one data chunk of the plurality of data chunks is unable to be read, the at least one data chunk corresponding to a failed data chunk. And in response to determining the failed data chunk, sending to the host interface the read data including the failed data chunk or excluding the failed data chunk. And in response to the read command sending to the host interface status information about all data chunks.

Methods, systems, and apparatuses for memory (e.g., DRAM) having an error check and scrub (ECS) procedure in conjunction with refresh operations are described. While a refresh operation reads the code words of a memory row, ECS procedures may be performed on some of the sensed code words. When the write portion of the refresh begins, a code word discovered to have errors may be corrected before it is written back to the memory row. The ECS procedure can be incremental across refresh operations, beginning, for example, each ECS at the code word where the pervious ECS for that row left off. The ECS procedure can include an out-of-order (OOO) procedure where ECS is performed more often for certain identified code words.

A plurality of computing devices are communicatively coupled to each other via a network, and each of the plurality of computing devices is operably coupled to one or more of a plurality of storage devices. One or more of the computing devices and/or the storage devices may be used to rebuild data that may be lost due to a power failure.

Disclosed is a system that comprises a memory device and a processing device, operatively coupled with the memory device, to perform operations that include, determining that a value of a write counter associated with the memory device satisfies a first threshold criterion. The operations performed by the processing device further include, responsive to determining that the value of the write counter satisfies the first threshold criterion, identifying a first memory unit and a second memory unit of the memory device, the second memory unit comprising one or more memory cells adjacent to one or more memory cells of the first memory unit. The operations performed by the processing device further include performing a read operation on the second memory unit to determine a set of failed bit count statistics corresponding to a plurality of codewords of the second memory unit. The operations performed by the processing device further include determining that the set of failed bit count statistics corresponding to the plurality of codewords of the second memory unit satisfies a second threshold criterion. The operations performed by the processing device further include, responsive to determining that the set of failed bit count statistics corresponding to the plurality of codewords of the second memory unit satisfies the second threshold criterion, performing a write scrub operation on the second memory unit.
