Abstract
Methods, systems, and devices for scratchpad memory in a cache are described. A device may operate a portion of a volatile memory in a cache mode having non-deterministic latency for satisfying requests from a host device. The device may monitor a register with an output pin that is associated with the portion and indicative of an operating mode of the portion. Based on or in response to monitoring the output pin, the device may determine whether to change the operating mode of the portion from the cache mode to a scratchpad mode having deterministic latency for satisfying requests from the host device.
