    Abstract: A high-bandwidth memory (HBM) system includes an HBM device and a logic circuit. The logic circuit includes a first interface coupled to a host device and a second interface coupled to the HBM device. The logic circuit receives a first command from the host device through the first interface and converts the received first command to a first processing-in-memory (PIM) command that is sent to the HBM device through the second interface. The first PIM command has a deterministic latency for completion. The logic circuit further receives a second command from the host device through the first interface and converting the received second command to a second PIM command that is sent to the HBM device through the second interface. The second PIM command has a non-deterministic latency for completion.

    Abstract: A method of performing memory deduplication and single error correction double error detection (SEC-DED) in a computer memory, the method including reading data from an array of memory chips, calculating at least one hash based on the data, checking the one or more hashes against at least one of a physical line ID hash and against a secondary hash, determining whether an error is detected, when an error is detected, correcting the data by changing each bit of the array of the memory chips one at a time until no error is detected, wherein between changing each bit, at least one hash is calculated based on the changed data, and the one or more hash for the new data is compared against one or more of a physical line ID hash and against a secondary hash, and again determining whether an error is detected, and outputting the corrected data when no error is detected.

    Abstract: According to some example embodiments of the present disclosure, in a method for a memory lookup mechanism in a high-bandwidth memory system, the method includes: using a memory die to conduct a multiplication operation using a lookup table (LUT) methodology by accessing a LUT, which includes floating point operation results, stored on the memory die; sending, by the memory die, a result of the multiplication operation to a logic die including a processor and a buffer; and conducting, by the logic die, a matrix multiplication operation using computation units.
