Embodiment Construction

[0013] Some memory systems, including flash memory systems, may include processing capabilities such as onboard processors, central processing units (CPUs), application specific integrated circuits (ASICs), or other processors that may communicate with one or more memory arrays of the memory system. included in the same package. Such processing power supports various operations at the memory system, such as address mapping or translation, Tightly Coupled Memory (TCM) technology, Inter-Process Communication (IPC) technology, array redundancy technology, caching, wear leveling, and other information management or array management technology. In some memory systems, processing capabilities may be associated with (e.g., supported by) information stored at the memory system, such as firmware tables or cache information, which may involve storing the processing information at the memory system in association with In a memory-separated memory array representing information stored by...

Abstract

The invention relates to transferring memory system data to an auxiliary array. A memory system may be configured for transferring information between a relatively volatile memory array and a relatively non-volatile memory array in response to transitions between various operating modes, such as operating modes associated with different operating power levels. For example, before entering a reduced power mode, the memory system may identify information stored in a volatile memory array and transfer the identified information to an auxiliary, non-volatile memory array. Such information may be returned to the relatively volatile memory array to support memory system operation after exiting the reduced power mode. In some examples, such information exchanged between the memory system and the host system may be associated with a processing capability of the memory system, and the described operations may be referred to as suspending memory system processing information to an auxiliary array.

Description

[0001] cross reference [0002] This patent application asserts U.S. Serial No. 16 / 989,599, filed August 10, 2020, by Grosz et al., entitled "TRANSFERRING MEMORY SYSTEM DATA TO AN AUXILIARY ARRAY" priority to the patent application, assigned to the present assignee and expressly incorporated herein by reference in its entirety. technical field [0003] The technical field relates to transferring memory system data to a secondary array. Background technique [0004] Memory devices are widely used to store information in various electronic devices such as computers, wireless communication devices, cameras, digital displays, and the like. Information is stored by programming memory cells within a memory device into various states. For example, a binary memory cell can be programmed to one of two supported states, often corresponding to a logical one or a logical zero. In some examples, a single memory cell can support more than two possible states, either of which the memor...
