Abstract: Adaptively changing a fail bit count for an erase operation is disclosed. A memory system may detect an erase stuck bit condition in a group of memory cells. An erase stuck bit condition refers to a situation in which the threshold voltage of at least one memory cell on string tends to stick, such that the string cannot be erased. The memory system performs an action in response to detecting an erase stuck bit condition, in one embodiment. One possible action is to increase a fail bit count for erase operations for other groups of memory cells, which could also potentially suffer from erase bit stuck conditions. This can help reduce erase stress on groups of memory cells. It can also reduce the number of groups of memory cells that need to be retired for failing an erase operation.

Abstract: Systems, methods, and/or devices are used to manage open blocks within non-volatile storage devices, in order to improve the reliability of non-volatile storage devices. In some embodiments, when a shut-down request is received from a host device, the storage device fetches information about open blocks and their boundary regions susceptible to data reliability issues, and for each identified boundary region, the storage device programs a region contiguous to the identified boundary region. In some embodiments, the device updates an XOR parity table used for XOR parity management with the information that the region contiguous to the identified boundary is programmed. Subsequently, in some embodiments, the storage device can use the information, stored in the contiguous region and/or the XOR parity table, for data recovery in the event of a data loss. As a result, the reliability of the non-volatile storage device is improved.

Abstract: A dual input power supply system/method providing uninterruptable power to a protected load device (PLD) is disclosed. The system includes hybrid switch devices (HSD) comprising semiconductor and relay/contactors that minimize the OPERATE/RELEASE times associated with switchover from a primary power source (PPS) to a secondary power source (SPS). An operate/release controller (ORC) monitors the condition of power provided by the PPS and SPS and determines the optimal transfer time to activate the HSD and switch between the PPS and SPS based on the PLD configuration. Use of the HSD in conjunction with the ORC permits a wide variety of series permutated AC/DC primary (PPS) and secondary (SPS) power sources, EMI snubbers (EMS), bridge rectifier diodes (BRD), AC-DC converters (ADC), and DC-DC converters (DDC) to service the PLD, while simultaneously reducing storage capacitors normally required to cover the OPERATE/RELEASE times associated with traditional PPS/SPS switchover/failover delays.
