  • Patent number: 10923450
    Abstract: An integrated circuit memory includes a logic circuitry bonded to a memory array. For example, the logic circuitry is formed separately from the memory array, and then the logic circuitry and the memory array are bonded. The logic circuitry facilitates operations of the memory array and includes complementary metal-oxide-semiconductor (CMOS) logic components, such as word line drivers, bit line drivers, sense amplifiers for the memory array. In an example, instead of being bonded to a single memory array, the logic circuitry is bonded to and shared by two memory arrays. For example, the logic circuitry is between two memory arrays. Due to the bonding process, a bonding interface layer is formed. Thus, in such an example, a first bonding interface layer is between the logic circuitry and a first memory array, and a second bonding interface layer is between the logic circuitry and a second memory array.
