  • Publication number: 20250004662
    Abstract: In accordance with described techniques for read gate training and tracking, a computing device includes a memory system (e.g., dynamic random access memory (DRAM)) that receives a memory read operation which includes a memory clock that correlates to a physical layer (PHY) clock. The computing device includes a PHY that receives a return data signal from the memory system, where the return data signal includes a returned data strobe that is out-of-phase with respect to the PHY clock. The computing device includes training logic that utilizes edge detection to determine an unknown clocking phase of the returned data strobe with respect to the PHY clock. The computing device also includes tracking logic that utilizes the edge detection to detect a signal drift of the delay signal with respect to the returned data strobe and compensate for the drift.

  • Publication number: 20240329839
    Abstract: Clock domain phase adjustment techniques and systems for memory operations are described. In one example, a physical memory is communicatively coupled to a physical layer via a first clock domain and a memory controller is communicatively coupled to the physical layer via a second clock domain that is different than the first clock domain. A buffer is implemented in the physical layer. The buffer is configured to set a phase adjustment for a latency setting between the first and second clock domains. The phase adjustment is based on whether a mismatch has occurred in data output by the buffer to the memory controller based on a comparison to the latency setting.

    Abstract: A constant power control device of an active vaporization suction apparatus includes a power unit, a first load matching unit, a matching control unit, a second load matching unit, and a constant current generation unit. To replace a medication box along with a liquefied medication within, a new medication box is mounted on the constant power control device, and the first load matching unit is electrically connected to a load unit of the replaced medication box. The first load matching unit determines a load value of the load unit. The second load matching unit and the constant current generation unit generate a constant current signal according to the load value, and transmit the constant current signal to the load unit, thus allowing the load unit to vaporize the liquefied medication with a constant power. The present invention prevents the constant power from changing due to medication box replacements.

  • Publication number: 20240198019
    Abstract: The present invention is an active vaporization suction system and a controlling method thereof. The system includes a medication device and an active suction device. The medication device is detachably mounted on the active suction device. When a suction module is suctioned, a flow module outputs a launching signal to a control module. The control module outputs a vaporization current control signal to a power supply module according to the launching signal. The power supply module generates and outputs a Joule vaporization current to a Joule vaporizer of the medication device according to the vaporization current control signal, so that the Joule vaporizer vaporizes a liquefied medication in a vaporization chamber into a vapor medication. In this way, when the user actively sucks the suction module, the user can take the vapor medication for medical treatment, which increases an absorption rate of the vapor medication.

  • Patent number: 11456052
    Abstract: Systems and methods of write deskew training for ×4 mode memory control interface configurations. Write leveling logic in the memory controller is adjusted to obtain a write leveling setting for delaying both first and second strobe signals associated with a byte. The adjustment is based on feedback of first set of bits of a byte and irrespective of the feedback of the second set of bits of the byte. The write leveling logic is then anchored at the write leveling setting, and a deskew delay line for the second strobe signal is adjusted to obtain a first deskew setting based on the feedback of the second set of bits. Thus, in write operations, the write leveling setting can be common within the byte even the two strobe signals are transmitted to or received from two different memory storage devices.

  • Patent number: 10649025
    Abstract: A byte lane of an integrated circuit including two data strobe loopback paths that allow external test signals to flow in and out of the integrated circuit through data strobe pins in two opposite directions. The integrated circuit includes a Feed Forward Equalization (FFE) path configured to send FFE signals output from the FFE logic via a transmitter set to a first data strobe interface during a normal operation. In a loopback test mode operation, a test signal can be supplied from a second data strobe interface and output to the first data strobe interface by reusing the FFE path. The second loopback path conversely allows a test signal to be routed from the first data strobe interface to the second.

  • Patent number: 10497413
    Abstract: System and method of read deskew training for ×4 mode memory control interface configurations. A read deskew training process includes aligning the two strobe signals serving one byte before deskewing the data bits against their corresponding strobe signals. A deskew setting of a variable delay line associated with the second strobe signal is adjusted to align the second strobe signal with reference to the first strobe signal. By aligning the two strobe signals with respect to each other, the read leveling settings can be common within the byte even the two DQS signals are transmitted to or received from two different memory storage devices.
