Abstract: Various implementations described herein refer to a device having an encoder coupled to memory. The ECC encoder receives input data from memory built-in self-test circuitry, generates encoded data by encoding the input data and by adding check bits to the input data, and writes the encoded data to memory. The device may have an ECC decoder coupled to memory. The ECC decoder reads the encoded data from memory, generates corrected data by decoding the encoded data and by extracting the check bits from the encoded data, and provides the corrected data and double-bit error flag as output. The ECC decoder has error correction logic that performs error correction on the decoded data based on the check bits, wherein if the error correction logic detects a multi-bit error in the decoded data, the error correction logic corrects the multi-bit error in the decoded data to provide the corrected data.

Abstract: Packet recovery mechanisms for wireless networks, which improve end-to-end (e2e) reliability, are provided. First embodiments include packet retransmission between a receiver and a transmitter, wherein, if the transmitter cannot find a lost packet in its transmission buffer, the transmitter sends a First Sequence Number (FSN) report to the receiver to notify the receiver of a sequence number (SN) of an oldest (acknowledged) packet in the buffer. In response, the receiver does not report lost packets whose SN is older than the FSN. Second embodiments involve using a network coding algorithm to recover lost packets, wherein the transmitter sends a control message to the receiver that includes a coded packet to be recovered and information for decoding the coded packet. Other embodiments may be described and/or claimed.

Abstract: An address fault detection system includes write and read access circuits and a fault management circuit. The write access circuit receives an address and reference data for a write operation associated with a memory and parity data generated based on the reference data, and writes the reference data and the parity data to first and second memory blocks of the memory, respectively. The read access circuit receives the same address for a read operation associated with the memory and reads another reference data and another parity data from the first and second memory blocks, respectively. The fault management circuit compares the read parity data with parity data generated based on the read reference data to detect an address fault in the memory. The written and read reference data are different when the address fault is detected, and same when the address fault is not detected.

Abstract: A fault tolerant quantum error correction protocol is implemented for a surface code comprising Gottesman Kitaev Preskill (GKP) qubits. Analog information is determined when measuring position or momentum shifts, wherein the analog information indicates a closeness of the shift to a decision boundary. The analog information is further used to determine confidence values for error corrected measurements from the GKP qubits of the surface code. These confidence values are used to dynamically determine edge weights in a matching graph used to decode syndrome measurements of the surface code, wherein the confidence values are obtained using a maximum-likelihood decoding protocol for two-qubit gates. Space-time correlated edges and other edges are included in the matching graph and weighted based at least in part on confidence values for qubits forming the respective edges.

Abstract: Technology is disclosed herein for managing parity data in non-volatile memory. As user data is programming into respective groups of non-volatile memory cells, the system accumulates parity data. The system may accumulate XOR parity based on successive bitwise XOR operations of user data. After programming is complete, the system performs a post-program read test of the data stored into each respective group of memory cells. The system re-calculates the parity data such that the parity data is no longer based on the user data that was stored in any group of memory cells for which the post-program read test failed. For example, the system will perform an additional bitwise XOR between the accumulated XOR parity data with the user data that was stored in the group of memory cells for which the post-program read test failed. The parity data is programmed to a group of memory cells.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may transmit feedback, such as hybrid automatic repeat request (HARD) feedback for groups of code blocks rather than for an entire transport block or individual code blocks. The wireless device may transmit an acknowledgement (ACK) or negative-acknowledgement (NACK) to provide feedback for each code block group of a set of code block groups. An ACK may indicate that code blocks in a code block group were successfully decoded, and a NACK may indicate that at least one code block in a code block group was not successfully decoded. Wireless devices may support several techniques for grouping code blocks for feedback reporting to allow for efficient retransmissions and limited overhead. Different grouping schemes may be employed depending on system constraints, device capability, link conditions, or the like.
