  • Patent number: 12292601
    Abstract: Command/address and timing information is distributed to buffer integrated circuits on a module using multiple wavelengths of light modulated with the same information. Each individual wavelength of modulated light carrying command/address information is received by a corresponding single buffer device that deserializes the command/address information and communicates it electrically to memory devices(s). Likewise, each individual wavelength of modulated light carrying timing/synchronization/clock information is received by a corresponding single buffer device and used to synchronize accesses to the memory device(s). Thus, multiple buffer integrated circuits on a module each receive information from the CPU using different wavelengths of light transmitted on the same waveguide.

  • Patent number: 12287712
    Abstract: Described are memory systems and devices in which each memory die in a three-dimensional stack of memory dies includes drive and receive circuitry that can communicate data signals from the stack on behalf of all the memory dies in the stack. The drive and receive circuitry, if defective on one device in the stack, can be disabled and substituted with the drive and receive circuitry from another. The stack of memory dies can thus function despite a failure of drive or receive circuitry in one or more of the memory dies. Each memory die includes test circuitry to detect defective drive and receive circuitry.

  • Publication number: 20250124273
    Abstract: An integrated-circuit neural network includes chain of multiply-accumulate units co-located with a high-bandwidth storage array. Each multiply accumulate includes a digital input port, analog input port and multiply-adder circuitry. The digital input port receives a matrix of digital-weight values from the storage array and the analog input port receives a counterpart matrix of analog input signals, each analog input signal exhibiting a respective electronic current representative of input value. The multiply-adder circuitry generates a matrix of analog output signals by convolving the matrix of digital-weight values with the matrix of analog input signals including, for each analog output signal within the matrix of analog output signals, switchably enabling weighted current contributions to the analog output signal based on logic states of on respective bits of one or more of the digital-weight values.

  • Publication number: 20250061935
    Abstract: An interposer interconnecting a first integrated circuit and a second integrated circuit includes active circuitry. The “active” interposer converts high-speed signals into lower-speed, but more parallelized, signals for transmission across the active interposer. The parallelized signals may be buffered or amplified at intervals while crossing the active interposer. The high-speed to low-speed, and back, conversions may be performed by an appropriately configured and controlled multiplexer/demultiplexer circuitry The supply voltages for some interposer circuits may be different than the supply voltages for the interfaces with the first and second integrated circuit. One or more of the interconnected integrated circuits may supply, and/or calibrate the supply voltages for the interposer circuitry. Timing signals provided by one or more of the interconnected integrated circuits may also be calibrated using circuitry on the active interposer.

  • Publication number: 20240370361
    Abstract: Multiple (e.g., four) memory devices on a module are connected to a common pair of differential data strobe signal conductors. The common pair of differential data strobe conductors are also coupled to a memory controller to time the transmission of data to the multiple memory devices and to time the reception of data from the memory devices. The controller calibrates two or more different data transmission delays relative to its transmission of a write data strobe signal on the common pair of differential data strobe conductors. The controller also calibrates to account for two or more different data reception delays (skew) relative to its reception of a read data strobe signal on the common pair of differential data strobe conductors.

    Abstract: A four-channel memory module includes four independent twenty (20) data bit memory channels and dual channel memory devices. The channels of the dual channel memory are accessed independently. Thus, the four channels for accessing the memory module each access one channel of a first set and a second set of dual channel memory devices on the module. Error detection and correction codeword configurations and schemes can implement chipkill, Single symbol data correct/double symbol data detect (SSDC/DSDD). Single symbol data correct with fewer memory devices may also be implemented. Error detection and correction codeword configurations and schemes may be switched in response to detecting a failed device, signal line, or memory channel.

  • Patent number: 11750426
    Abstract: A signal transmitter circuit includes an output driver circuit configured to transmit a signal using a multi-level pulse amplitude modulation (PAM) scheme comprising a plurality of discreet signal levels. During operation, the output driver initiates a first transition of the signal to a first level of the multi-level PAM scheme from a second level of the multi-level PAM scheme, and initiates a second transition of the signal to the first level from a third level of the multi-level PAM scheme. The signal transmitter further includes a control circuit configured to control a slew rate of the signal transmitter circuit to cause the signal to reach a threshold voltage level at a first time, the first time occurring a first duration of time after the first transition is initiated, and to cause the signal to reach the threshold voltage level at a second time, the second time occurring the first duration of time after the second transition is initiated.
