Abstract: A controller includes an interface and a processor. The interface is configured to communicate with a nonvolatile memory including multiple memory cells organized in multiple memory blocks that each includes multiple Word Lines (WLs). The processor is configured to store first data in one or more WLs of a memory block, the first data occupies less than a maximal number of WLs available in the memory block, to calculate redundancy data over the first data and store the redundancy data in a dedicated memory, to program second data to a selected WL of the memory block that was not programmed with the first data, to check a programming status resulting from the programming of the selected WL, and in response to identifying that programming the second data to the selected WL has corrupted at least part of the first data, to recover the first data using the redundancy data.

Abstract: A controller includes an interface and a processor. The interface is configured to communicate with a memory including multiple memory cells organized in at least two sections each including multiple sets of word lines (WLs), wherein in a first failure mode multiple WLs fail in a single section, and in a second failure mode a WL fails in multiple sections. The processor is configured to assign multiple cell-groups of the memory cells to a parity-group, such that (i) no two cell-groups in the parity-group belong to a same WL, and (ii) no two cell-groups in the parity-group belong to adjacent WLs in a same section, and, upon detecting a failure to access a cell-group in the parity-group, due to either the first or second failure modes but not both failure modes occurring simultaneously, to recover the data stored in the cell-group using one or more remaining cell-groups in the parity-group.

Abstract: An apparatus includes a register memory and circuitry. The register memory is configured to hold a minimal value specified for a performance measure of a given type of memory access commands, whose actual performance measures vary among memory devices. The circuitry is configured to receive a memory access command of the given type, to execute the received memory access command in one or more memory devices, and to acknowledge the memory access command not before reaching the minimal value stored in the register memory.

Abstract: A method includes receiving one or more storage commands and at least one flush command in a storage device, which includes a non-volatile memory and a volatile buffer for buffering data received for storage in the non-volatile memory. The flush command instructs the storage device to commit the data buffered in the volatile buffer to the non-volatile memory. The storage commands are executed in accordance with a first storage rule. The flush command is executed in accordance with a second storage rule having smaller latency relative to the first storage rule.

Abstract: In a wireless communications system, during a base station or cell monitoring procedure, a device, system, and method may enable a communication device to determine if a serving base station is transmitting an adequate signal, and, if the base station is not transmitting an adequate signal, identifying another base station that may provide adequate service. For example, it may be determined if at least one other base station in a list of previously identified base stations transmits adequate signals. If this is not the case, a scan may be performed of a set of channels to identify further base stations or cells.
