摘要： Techniques for coding and decoding redundant coding for column defects cartography. Defective cell groups identified in a memory array are redundantly encoded with a different bit pattern than the bit pattern used for functional cell groups. The identified defective cell groups are repaired using redundant cell groups in the memory array. The defective cell groups are later re-identified by checking the redundant bit pattern encoded in the cell groups. If new defective cell groups are identified, the memory array is identified as failing. If no new defective cell groups are identified, the memory array is identified as passing, and the identified defective cell groups are repaired.

摘要： A subset of software objects stored in a first segment of non-volatile memory are identified as requiring frequent write operations or otherwise associated with a high endurance requirement. The subset of software objects are move to a second segment of non-volatile memory with a high endurance capacity, due to the application of wear leveling techniques to the second segment of non-volatile memory. The first and second segments of memory can be located in the same memory device or different memory devices.

摘要： The invention relates to a method for managing the endurance of a data storage system provided with a set of sectors endowed with a guaranteed native endurance capacity (G), comprising the steps consisting in:—partitioning said data storage system into a plurality of work sectors, and into a plurality of replacement sectors able to form an endurance reservoir, certain of the work sectors being intended to be replaced by replacement sectors when said work sectors are expended after a certain number of programming and/or erasure cycles;—defining an address management area making it possible to retrieve the location of the replacement sectors assigned to expended work sectors;—determining, sector by sector, whether a current work sector is physically expended, and executing a step of replacing this work sector by a replacement sector, only when said current work sector is declared physically expended. This method of managing endurance is in particular characterized in that in order to measure the expenditure of a sector, automatic reading of the quality of erasure of the memory points of the sector with respect to a severized reading criterion (margin Vref.) is carried out, that is to say one which is more severe than a normal criterion (Normal Vref.).

摘要： A content-addressable memory (CAM) for managing the reallocation of erasable objects within a non-volatile memory is conceptually separated into two tables: a first table provides verification of whether or not a logical address has been reallocated and, if so, a second table provides the physical address of the reallocated erasable object.

摘要： In a device having a plurality of circuits that can store at least a first value and a second value, a method can include configuring at least one circuit to persistently store the first value; determining whether the at least one circuit is storing the second value; and initiating a countermeasure if the at least one circuit is storing the second value. Determining whether the at least one circuit is storing the second value can include detecting whether the device has been attacked. Non-limiting examples of initiating a countermeasure can include resetting a portion of the device, powering down a portion of the device, activating an alarm circuit, causing protected data stored in the device to be erased, causing portions of the device to self-destruct, or causing the device to not respond to input applied to the interface.
