    摘要: A semiconductor mass storage device can be substituted for a rotating hard disk. The device avoids an erase cycle each time information stored in the mass storage is changed. (The erase cycle is understood to include, fully programming the block to be erased, and then erasing the block.) Erase cycles are avoided by programming an altered data file into an empty mass storage block rather than over itself as a hard disk would. Periodically, the mass storage will need to be cleaned up. Secondly, a circuit for evenly using all blocks in the mass storage is provided. These advantages are achieved through the use of several flags, a map to directly correlate a logical address of a block to a physical address of that block and a count register for each block. In particular, flags are provided for defective blocks, used blocks, old version of a block, a count to determine the number of times a block has been erased and written and erase inhibit.

    摘要: The present disclosure includes methods, devices, modules, and systems for operating semiconductor memory. A number of method embodiments include reading data from memory cells corresponding to a sector of data, determining a number of the memory cells in a non-erased state, and, if the number of the memory cells in a non-erased state is less than or equal to a number of errors correctable by an ECC engine, determining the sector is erased.

    摘要: A memory device includes a memory array with random defective memory cells. The memory array is organized into rows and columns with a row and column identifying a memory location of a memory cell of the memory array. The memory device includes a row address device and a column address device and is operative to use a grouping of either the row or the column addresses to manage the random defective memory cells by mapping the memory location of a defective memory cell to an alternate memory location.

    摘要: A magnetic memory device includes a main memory made of magnetic memory, the main memory and further includes a parameter area used to store parameters used to authenticate data. Further, the magnetic memory device has parameter memory that maintains a protected zone used to store protected zone parameters, and an authentication zone used to store authentication parameters, the protection zone parameters and the authentication parameters being associated with the data that requires authentication. Upon modification of any of the parameters stored in the parameter memory by a user, a corresponding location of the parameter area of the main memory is also modified.

    摘要: The present disclosure includes methods and devices for memory block selection. In one or more embodiments, a memory controller includes control circuitry coupled to one or more memory devices having multiple Groups of planes associated therewith, each Group including at least two planes of physical blocks organized into Super Blocks, with each Super Block including a physical block from each of the at least two planes. The control circuitry is configured to receive a first unassigned logical block address (LBA) associated with a write operation and determine a particular free Super Block within a selected one of the multiple Groups to receive data associated with the write operation.
