摘要： A memory system and methods of its operation are presented. The memory system includes a volatile buffer memory and a non-volatile memory circuit, where the non-volatile memory circuit has a first section, where data is stored in a binary format, and a second section, where data is stored in a multi-state format. When writing data to the non-volatile memory, the data is received from a host, stored in the buffer memory, transferred from the buffer memory to into read/write registers of the non-volatile memory circuit, and then written from the read/write registers to the first section of the non-volatile memory circuit using a binary write operation. Portions of the data and then subsequently folded from the first section of the non-volatile memory to the second section of the non-volatile memory, where a folding operation includes reading the portions of the data from multiple locations in the first section into the read/write registers and performing a multi-state programming operation of the potions of the data from the read/write registers into a location the second section of the non-volatile memory. The multi-state programming operations include a first phase and a second phase and one or more of the binary write operations are performed between the phases of the multi-state programming operations.

摘要： In a nonvolatile memory with a block management system, data written to blocks include host write data and also system control data for managing the blocks. When a block is full or no longer accepting data, it is closed after valid versions of the data on it are relocated to another block in a rewrite operation. An improved pre-emptive rewrite scheme prevents a worst-case situation where multiple rewrites to occur at once when they happened to be full at the same time. Particularly, the scheduling of the pre-emptive rewrites for control data is based on a number of considerations including the time required for each control block rewrite and the time available for control block rewrites based on the configuration of the update blocks for storing host data, the time required in the foreground host operation and the host write latency.

摘要： A non-volatile memory organized into flash erasable blocks sorts units of data according to a temperature assigned to each unit of data, where a higher temperature indicates a higher probability that the unit of data will suffer subsequent rewrites due to garbage collection operations. The units of data either come from a host write or from a relocation operation. Among the units more likely to suffer subsequent rewrites, a smaller subset of data super-hot is determined. These super-hot data are then maintained in a dedicated portion of the memory, such as a resident binary zone in a memory system with both binary and MLC portions.

摘要： A method and system pre-emptively perform garbage collection operations of a forced amount on update blocks in a memory device. The amount of garbage collection needed by a certain data write is monitored and adjusted to match the forced amount if necessary. Update blocks may be selected on the basis of their recent usage or the amount of garbage collection required. Another method and system may store control information about update blocks in a temporary storage area so that a greater number of update blocks are utilized. The sequential write performance measured by the Speed Class test may be optimized by using this method and system.

摘要： A non-volatile memory system includes a memory section having a non-volatile cache portion storing data in a binary format, a primary user data storage section that stores user data in multi-state format, and an update memory area where the memory system stores data updating user data previously stored in the primary user data. The memory system allows a maximum number of blocks for use in the update memory area. When the memory system receives updated data corresponding to user data already written into the primary user data storage section, it determines whether a block of memory is available in the update memory area. In response to determining that a block of memory is not available in the update memory area, the system determines a block of the update memory to remove from the update memory; copies the data content of the determined update block into the cache portion of the memory section; and subsequently writes the updated data into the update memory.

摘要： In a nonvolatile memory array, blocks that contain only obsolete data are modified by adding charge to their cells, increasing the charge level from the programmed charge levels that represented obsolete data to elevated charge levels. The increase in overall charge in such blocks lessens the tendency of such blocks to impact data retention in neighboring blocks.

摘要： A method and system for performing garbage collection operations on update blocks in a memory device using volatile memory is disclosed. When performing a garbage collection operation, a first part of the data related to the garbage collection operation is written to a volatile memory in the memory device, and a second part of the data related to the garbage collection operation is written to a non-volatile memory in the memory device. The first part of the data that is written to the volatile memory (such as a random access memory) may comprise control information (such as mapping information of the logical addressable unit to a physical metablock). The second part of the data related to the garbage collection that is written to the non-volatile memory (such as a flash memory) may comprise the consolidated data in the update block.
