Systems and methods are disclosed including a processing device operatively coupled to a first and a second memory device. The processing device can receive a set of data access requests, from a host system, in a first order and execute the set of data access requests in a second order. The processing device can further identify a late data access request of the set of data access requests and determine whether a data structure in a local memory associated with the processing device includes a previous outstanding data access request corresponding to an address associated with the late data access request. Responsive to determining that the data structure includes an indication of a previous outstanding data access request corresponding to the address associated with the late data access request, identifying a type of data dependency associated with the previous outstanding data access request and performing one or more operations associated with the type of data dependency.

Managing data dependencies for out of order processing in a hybrid DIMM

Systems and methods are disclosed including a first memory component, a second memory component having a lower access latency than the first memory component and acting as a cache for the first memory component, and a processing device operatively coupled to the first and second memory components. The processing device can perform operations including receiving a data access operation and, responsive to determining that a data structure includes an indication of an outstanding data transfer of data associated with a physical address of the data access operation, determining whether an operation to copy the data, associated with the physical address, from the first memory component to the second memory component is scheduled to be executed. The processing device can further perform operations including determining to delay a scheduling of an execution of the data access operation until the operation to copy the data is executed.

Managing data dependencies in a transfer pipeline of a hybrid dimm

Systems and methods are disclosed including a first memory device, a second memory device coupled to the first memory device, where the second memory device has a lower access latency than the first memory device and acts as a cache for the first memory device. A processing device operatively coupled to the first and second memory devices can track access statistics of segments of data stored at the second memory device, the segments having a first granularity, and determine to update, based on the access statistics, a segment of data stored at the second memory device from the first granularity to a second granularity. The processing device can further retrieve additional data associated with the segment of data from the first memory device and store the additional data at the second memory device to form a new segment having the second granularity.
