Abstract: Methods, systems, and apparatuses related to memory operation with multiple sets of latencies are disclosed. A memory device or system that includes a memory device may be operable with one or several sets of latencies (e.g., read, write, or write recovery latencies), and the memory device or system may apply a set of latencies depending on which features of the memory device are enabled. For example, control circuitry may be configured to enable one or more features during operations on a memory array, and the control circuitry may apply a set of latency values based on a number or type of features that are enabled. The sets of latency values may depend, for example, on whether various control features (e.g., dynamic voltage frequency scaling) are enabled, and a device may operate within certain frequency ranges irrespective of other characteristics (e.g., mode register values) or latencies applied.
