Abstract: A memory module may include one or more memory devices, and a near-memory computing module coupled to the one or more memory devices, the near-memory computing module including one or more processing elements configured to process data from the one or more memory devices, and a memory controller configured to coordinate access of the one or more memory devices from a host and the one or more processing elements. A method of processing a dataset may include distributing a first portion of the dataset to a first memory module, distributing a second portion of the dataset to a second memory module, constructing a first local data structure at the first memory module based on the first portion of the dataset, constructing a second local data structure at the second memory module based on the second portion of the dataset, and merging the first and second local data structures.

Abstract: A high-bandwidth memory (HBM) system includes an HBM device and a logic circuit. The logic circuit receives a first command from the host device and converts the received first command to a processing-in-memory (PIM) command that is sent to the HBM device through the second interface. A time between when the first command is received from the host device and when the HBM system is ready to receive another command from the host device is deterministic. The logic circuit further receives a fourth command and a fifth command from the host device. The fifth command requests time-estimate information relating to a time between when the fifth command is received and when the HBM system is ready to receive another command from the host device. The time-estimate information includes a deterministic period of time and an estimated period of time for a non-deterministic period of time.

Abstract: According to one general aspect, an apparatus may include a random access memory array that, in turn, includes a reconfigurable look-up table. The reconfigurable look-up table may include memory cells configured to simultaneously store a plurality of look-up tables, wherein each look-up table is associated with a respective logic function. The reconfigurable look-up table may include a local row decoder configured to activate one or more rows of memory cells based upon a set of input signals. The reconfigurable look-up table may be configured to perform one logic function at a time, and wherein the logic function is dynamically selected. The plurality of look up tables stored in the memory cells may be configured to be dynamically altered via a write operation to the random access memory array.

Abstract: A data structure and a mechanism to manage storage of objects is disclosed. The data structure can be used to manage storage of objects on any storage device, whether in memory or some other storage device. Given an object ID (OID) for an object, the system can identify a tuple that includes a device ID and an address. The device ID specifies the device storing the object, and the address specifies the address on the device where the object is stored. The application can then access the object using the device ID and the address.
