  • Patent number: 12094567
    Abstract: A computer system configured to overcome the conventional bottleneck of memory throughput. A wafer-on-wafer (WOW) technology is adapted to overcome the physical limitation of quantity and length in circuit deployments. The memory devices and the memory controllers in the logic circuit layer are improved to transmit data in differential signals. The differential signals can significantly reduce the error rate in high-speed transmissions, at a voltage level far lower than that of the conventional single-end signals. Thus, the power consumption of the computer system is significantly reduced. Furthermore, the memory controller in the computer system is improved to be an integrated controller having control over physical layer signals. Thereby, the conventional physical layer interface is no longer needed in the computer system, and therefore the cost to the computer system is further reduced.
