Abstract: Aspects of a storage device are provided for handling GBBs with defects between global interconnects and local word lines. The storage device includes a plurality of blocks each including a plurality of word lines, a plurality of interconnects within an interconnect set and between multiple ones of the blocks, volatile memory, and a controller. The controller determines a logical address pattern associated with the multiple ones of the blocks respectively including a program failure, determines whether the logical address pattern is associated with the interconnect set for the multiple ones of the blocks, determines a common word line associated with the program failures in the multiple ones of the blocks, un-marks these blocks as GBBs, and refrains from programming the common word line during respective program operations in the multiple ones of the blocks. Thus, blocks may be reclaimed, defective word line(s) isolated, and likelihood of read-only modes reduced.

Abstract: A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to determine that a power loss event has occurred, determine that one or more blocks are in an erased state, examine a block of the one or more blocks to determine whether the block is a SLC erased block or a TLC erased block, and place the block in a SLC pre-erase heap if the block is the SLC erased block or in a TLC pre-erase heap if the block is the TLC erased block. The controller is further configured to determine a first bit count of page0 for a SLC voltage for the block, determine a second bit count of page1 for a TLC voltage for the block, and classify the block as either a SLC erased block or a TLC erased block.

Abstract: A system and method for a power-cycle based read scrub of a memory device is provided. A controller stores an access counter which indicates a number of times a logical block address (LBA) has been accessed. When the LBA is accessed, the LBA counter is incremented. If the LBA counter indicates a count higher than a predetermined count, data stored in the LBA is duplicated and the duplicate data is stored as backup data. Subsequent access of the LBA will show that the LBA count is higher than the predetermined count, so the backup data will be accessed rather than the original LBA, thus preventing read-induced failure of the data which may be caused by further repeated access of the same LBA.

Abstract: A method is provided that includes performing a post-write read operation on a block of memory cells that includes a select gate transistor, and based on results of the post-write read operation selectively performing a select gate maintenance operation on the select gate transistor.

Abstract: In a family of telecommunications modules or other circuit boards, driver software is divided into a core support package for initializing board components common to the family of circuit boards and one or more extended support packages specific to individual members of the family. This facilitates a reduction in the amount of programming effort needed across the family of circuit boards as the core support package need only be developed once for the family of boards rather than developing complete driver programs for each member of the family. The remaining programming effort can then be focused on the specialized subroutines. In addition, changes in hardware common to each member of the family can be accommodated by redeveloping only the core program. This need only occur once for the entire family, rather than once for each member of the family.

Abstract: A watchdog device is refreshed using either a hardware strobe or a software output as the refresh strobe. The hardware strobe is selected when the software output is undesirable as the refresh strobe. Undesirability includes the inability of the software output to reliably refresh the watchdog device or an unknown ability of the software output to reliably refresh the watchdog device.

Abstract: A method of transferring data from a host system to a target system includes creating a data record for transmitting data to the target in which the record includes a starting address for loading a sequence of data into a memory of the target system, one or more error detection codes, and an uninterrupted sequence of data for loading sequentially into the memory.
