Abstract
Methods, systems, and devices for techniques for flexible self-refresh of memory arrays are described. A memory system may set a respective refresh region for each respective memory bank of the memory system by tracking access to memory row addresses in respective memory banks used in the respective memory banks. For example, the memory system may monitor respective access commands issued to each respective memory bank and store information in a register of each respective memory bank. The memory system may determine whether a respective memory row address associated with a respective access command is within the respective refresh region and process the respective memory bank. The memory system may update a value stored in a register of the respective memory bank (e.g., a memory row address value) to adjust the refresh region of the respective memory bank without updating refresh regions for other memory banks in the memory system.
