Abstract: Apparatuses, systems, methods, and computer program products for enhanced erase retry of a non-volatile storage device are disclosed. An apparatus includes a non-volatile storage device and a controller. A controller includes a verification component configured to detect that an erase operation performed on an erase block of a non-volatile storage device is unsuccessful. A controller includes a parameter component configured to adjust one or more erase parameters for an erase operation. One or more erase parameters may be associated with one or more select gate drain storage cells of an erase block. A controller includes an erase component configured to retry an erase operation on an erase block with one or more adjusted erase parameters.

Abstract: Apparatuses, systems, methods, and computer program products for programming an unprogrammed upper page based on lower page programming are disclosed. An apparatus includes a non-volatile storage device and a controller. A controller includes a data component that is configured to receive a write request for a first page of a set of multi-level storage cells of a non-volatile storage device. A set of multi-level storage cells includes a first page and a second page. A controller includes a page component that is configured to determine that a write request does not comprise data for at least a portion of a second page of a set of multi-level storage cells. A controller includes a write component that is configured to program at least a portion of a second page of a set of multi-level storage cells with data of a first page of a set of multi-level storage cells.

Abstract: A storage system and method for marginal write-abort detection using a memory parameter change is provided. In one embodiment, a method for detecting a write abort is provided that is performed in a storage system having a memory. The method comprises reading a lower page in memory; determining if any data is written in the lower page; and in response to determining that no data is written in the lower page: increasing source voltage for memory cells in the lower page; re-reading the lower page; determining if a read failure exists in the re-read lower page; and in response to determining that a read failure exists in the re-read lower page, detecting a write abort. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.

Abstract: A system having a split bus flash memory and a method for operating the split bus flash memory is disclosed. The system may include a controller, a non-volatile memory (including first and second non-volatile memory chips) and the system bus. The controller is configured to communicate via an N-bit bus. The first and second non-volatile memory chips are configured to communicate via an M-bit bus, with M<N. The system bus connects the controller with the first and second non-volatile memory chips, wherein the system bus is split with some of the system bus lines connected to the first non-volatile memory chip and other of the system bus lines connected to the second non-volatile memory chip. In this way, the controller may communicate command, address and/or data with the memory chips in parallel.
