Abstract: Systems, apparatuses, and methods related to access request management using sub-commands. Access requests received from a host system can be managed using a respective set of sub-commands corresponding to each access request and whose status can be tracked. Tracking how far access requests are processed at a fine granularity (of sub-commands) can provide efficient management of the access requests that can reduce a gap latency in processing multiple access requests.

Abstract: Various embodiments provide a memory system architecture for heterogeneous memory technologies, which can be implemented by a memory sub-system. A memory system architecture of some embodiments can support servicing an individual command request using different (heterogeneous) memory technologies, such as different types of memory devices (e.g., heterogeneous memory devices), different types of memory device controllers (e.g., heterogeneous memory device controllers), different types of data paths (e.g., data paths with different protocols or protocol constrains), or some combination thereof. According to various embodiments, the memory system architecture uses tracking and management of multiple command responses to service a single command request from a host system.

Abstract: Systems, apparatuses, and methods related to an adjustable timer component are described. A memory device includes, a memory controller coupled to the memory device comprising an adjustable timer component. The adjustable timer component is configured to receive a timer generation request and, responsive to receiving the request, store in a cache an active timer entry corresponding to a particular first address, generate a timer corresponding to an active timer entry and the particular first address, and monitor the timer to determine when the timer expires. Responsive to the expiration of the timer, dequeue the timer entry and invalidate the timer entry stored in the cache. The memory device can also include command logic configured to, prior to issuing a second command, query the cache of the adjustable timer component to determine if the cache includes an active timer entry corresponding to the particular second address.
