Abstract

A processing core includes a multi-core processor integrated directly onto a high bandwidth, high-capacity memory. The processor may for example be a large graphics processing unit (GPU) or artificial intelligence (AI) processor. The memory may include a non-volatile memory and a volatile memory. The non-volatile memory may comprise a CBA (CMOS bonded to array) memory tile having a single large NAND memory tile coupled together with a CMOS logic circuit tile. The volatile memory may comprise one or more DRAM memory tiles or the like. The processing core may further include stacks of high bandwidth memory (HBM) semiconductor dies affixed to the interposer around one or more sides of the processor, the one or more volatile memory tiles and CBA memory tile.
