Abstract: Methods, systems, and devices for memory die resource management are described. A resource manager can determine, from a set of global resources for multiple memory dies of a memory sub-system, a set of die-specific resources for a memory die of the multiple memory dies of the memory sub-system. In some case, the set of die-specific resources can be allocated for read commands for the memory die. The resource manager can assign a read command to a die-specific resource of the set of die-specific resources based on the die-specific resource being available and refrain from assigning the read command to the die-specific resource based on the die-specific resource being unavailable.

Abstract: A request to perform a program operation at a memory device is received. An entry of a device block record stored at the memory device is determined to be removed based on parameters associated with the program operation and a firmware block record that corresponds to the device block record. The firmware block record tracks the entries of the device block record. The entries of the device block record are associated with blocks of the memory device and identify start voltages that are applied to wordlines of the blocks to program memory cells associated with the wordlines. A command is submitted to the memory device to remove the entry associated with a particular block from the device block record and to make a space available at the device block record for a new entry associated with a new block that is to be written in view of the program operation.

Abstract: A processing device in a memory sub-system sends a program command to the memory device to cause the memory device to initiate a program operation on a corresponding wordline and sub-block of a memory array of the memory device. The processing device further receives a request to perform a read operation on data stored on the wordline and sub-block of the memory array, sends a suspend command to the memory device to cause the memory device to suspend the program operation, reads data corresponding to the read operation from a page cache of the memory device, and sends a resume command to the memory device to cause the memory device to resume the program operation.

Abstract: A program operation is executed on a memory sub-system. During execution of the program operation, a request to execute a read operation on the memory sub-system is received. In response to receiving the request, a program suspend operation to suspend the program operation is executed. The read operation is executed on the memory sub-system in response to a completion of the program suspend operation. In response to completion of the read operation, a program resume operation is executed. A program suspend delay period is established following execution of the program resume operation during which a subsequent read operation is stored in a queue.
