  • Publication number: 20240071436
    Abstract: A memory device includes a command interface configured to receive write commands from a host device. The memory device also includes an input buffer configured to buffer data from the host device. Additionally, the memory device includes a state machine configured to receive a command into a first partition of the state machine and to enable a data strobe (DQS) input buffer in response to the indication. The state machine is also configured to maintain the enablement of the DQS input buffer while the command traverses the state machine. Furthermore, the state machine is configured to disable the DQS input buffer after a set duration of time.

  • Publication number: 20240069589
    Abstract: An example memory apparatus includes clock circuitry. The clock circuitry can generate first and second clock signals based on a system clock signal, with the first and second clock signals being mutually out of phase. The apparatus can include detection circuitry to provide a detection result indicating whether an initial operation of a self-refresh exit operation coincides with a rising edge of the first clock signal or a rising edge of the second clock signal. The apparatus can include processing circuitry to provide an odd clock signal and an even clock signal based first and second clock signals and the detection result. The processing circuitry can provide the odd clock signal and the even clock signal out of phase or in phase with the first clock signal and the second clock signal depending on the detection result.

  • Patent number: 11804251
    Abstract: A memory device includes a command interface configured to receive a two-cycle command from a host device via multiple command address bits. The memory device also includes a command decoder configured to decode a first portion of the multiple command address bits in a first cycle of the two-cycle command. The command decoder includes mask circuitry. The mask circuitry includes mask generation circuitry configured to generate a mask signal. The mask circuitry also includes multiplexer circuitry configured to apply the mask signal to block the command decoder from decoding a second portion of the multiple command address bits in a second cycle of the two-cycle command.

  • Patent number: 11727979
    Abstract: Methods of operating a memory device are disclosed. A method may include asserting, at a semiconductor device, an internal signal in response to receipt of a command. The method may also include holding the internal signal in an asserted state for at least a predetermined time duration upon assertion of the internal signal. Further, the method may include generating an enable signal based on the internal signal and a clock signal. Associated devices and systems are also disclosed.

  • Patent number: 11605408
    Abstract: A memory device includes a command interface configured to receive a command from a host device via multiple command address bits. The memory device also includes a merged command decoder configured to receive the command and to determine whether the command matches a bit pattern corresponding to multiple command types. The merged command decoder is also configured to, in response to the command matching the bit pattern, asserting a latch signal. The memory device also includes a latch configured to capture the multiple command address bits based at least in part on assertion of the latch signal.

  • Publication number: 20230076261
    Abstract: Methods, apparatuses, and systems related to coordinating a set of timing-critical operations across parallel processing pipelines are described. The coordination may include selectively using (1) circuitry associated with a corresponding pipeline to generate enable signals associated with the timing critical operations when a separation between the operations corresponds to a number of pipelines or (2) circuitry associated with a non-corresponding or another pipeline when the separation is not a factor of the number of pipelines.

  • Patent number: 11574661
    Abstract: The systems and methods described herein involve a device that may receive a plurality of commands and generate a common command indicative of matching data signals between each of the plurality of commands. The device may include a first latch that receives a shifted flag and outputs a shifted command in response to a first enable signal. The device may include shifters, where a first shifter may receive the common command, and a last shifter may couple to the first latch. The last shifter may receive a shifter common command and may generate the first enable signal using the shifted common command.
