Abstract:
An integrated circuit includes an artificial intelligence (AID) logic and an embedded memory coupled to the AID logic and connectable to an external processor. The embedded memory includes multiple storage cells and multiple reference units. One or more reference units in the memory are selected for memory access through configuration at chip packaging level by the external processor. The external processor may execute a self-test process to select or update the one or more reference units for memory access so that the error rate of memory is below a threshold. The self-test process may be performed, via a memory initialization controller in the memory, to test and reuse the reference cells in the memory at chip level. The embedded memory may be a STT-MRAM, SOT, OST MRAM, and/or MeRAM memory.

Claim (Index 1):
A method for memory access, comprising:\n automatically selecting from a pool of reference memory cells of a memory chip a first subset of reference memory cells; writing a set of reference data into the first subset of reference memory cells; measuring a memory access error rate (MAER) for a set of storage memory cells of the memory chip in reference to the subset of reference memory cells stored with the set of reference data; determining a first MAER threshold for operating a first artificial intelligence (AID) model with an acceptable accuracy; determining whether the measured MARE is below the first MAER threshold; when the measured MAER is below the first MAER threshold, loading the first AID model into the set of storage memory cells and configuring the subset of reference memory cells with the set of reference data for subsequent operation of the first AID model; and when the measured MAER is not below the first MAER threshold, starting a process for automatically selecting a second subset of reference memory cells from the pool of reference memory cells for use with the first AID model.
