Apparatuses, systems, and methods for low latency selection policy for memory commands

Abstract

Memory controller commands to be sent to a memory device may be prioritized based one or more factors. For instance, a memory controller may employ a first-ready, first-come, first-served (FRFCFS) policy in which certain types of commands (e.g., read) are prioritized over other types of commands (e.g., write). The policy may be modified so when deciding which bank to open, the bank with the oldest read command is opened. While continuing to issue commands per this modified FRFCFS policy, the controller may keep track of banks whose pages are ready to receive their respective read commands. Once a number of ready banks meets or exceeds a threshold, issuance of write commands are paused and read commands for the ready banks are issued.
