  • Patent number: 11682418
    Abstract: The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The head includes a main pole at a media facing surface (MFS), a trailing shield at the MFS, and a heavy metal layer disposed between the main pole and the trailing shield at the MFS. Spin-orbit torque (SOT) is generated from the heavy metal layer and transferred to a surface of the main pole as a current passes through the heavy metal layer in a cross-track direction. The SOT executes a torque on the surface magnetization of the main pole, which reduces the magnetic flux shunting from the main pole to the trailing shield. With the reduced magnetic flux shunting from the main pole to the trailing shield, write-ability is improved.

  • Patent number: 11682428
    Abstract: This application provides a hard disk format conversion method and apparatus, and a storage device, and belongs to the field of storage technologies. In this application, a storage format of a storage unit is converted from an SMR format to a PMR format. Because IOPS in the PMR format is higher than IOPS in the SMR format, IOPS in the storage unit can be increased after the storage format is converted. Alternatively, a storage format of a storage unit is converted from the PMR format to the SMR format. Because a storage capacity in the SMR format is higher than a storage capacity in the PMR format, a storage capacity of the storage unit can be increased after the storage format is converted.

  • Patent number: 11682439
    Abstract: Techniques herein may allow a row of a subarray in a bank of a memory device to be activated before a precharge operation has been completed for a previously opened row of memory cells in the same bank. Each subarray within the bank may be associated with a respective local latching circuit, which may be used to maintain phases at the subarray independent of subsequent commands to the same bank. For example, the latching circuit may internalize timing signals triggered by a precharge command for a first row such that if an activation command is received for a different subarray in the same bank at a time before the precharge operation of the first row is complete, the precharge operation may continue until the first row is closed, as the timing signals triggered by the precharge command may be maintained locally at the subarray using the latching circuit.

  • Patent number: 11682442
    Abstract: Technology for limiting a voltage difference between two selected conductive lines in a cross-point array when using a forced current approach is disclosed. In one aspect, the selected word line voltage is clamped to a voltage limit while driving an access current through a region of the selected word line and through a region of the selected bit line. The access current flows through the memory cell to allow a sufficient voltage to successfully read or write the memory cell, while not placing undue stress on the memory cell. In some aspects, the maximum voltage that is permitted on the selected word line depends on the location of the selected memory cell in the cross-point memory array. This allows memory cells for which there is a larger IR drop to receive an adequate voltage, while not over-stressing memory cells for which there is a smaller IR drop.

  • Patent number: 11682448
    Abstract: A system that calibrates timing relationships between signals involved in performing write operations is described. This system includes a memory controller which is coupled to a set of memory chips, wherein each memory chip includes a phase detector configured to calibrate a phase relationship between a data-strobe signal and a clock signal received at the memory chip from the memory controller during a write operation. Furthermore, the memory controller is configured to perform one or more write-read-validate operations to calibrate a clock-cycle relationship between the data-strobe signal and the clock signal, wherein the write-read-validate operations involve varying a delay on the data-strobe signal relative to the clock signal by a multiple of a clock period.

  • Patent number: 11682456
    Abstract: Methods for programming memory cells of a resistive memory device include applying a voltage pulse sequence to a memory cell to set a logic state of the memory cell. An initial set sequence of voltage pulses may be applied to the memory cell, followed by a reform voltage pulse having an amplitude greater than the amplitudes of the initial set sequence, and within ±5% of the amplitude of a voltage pulse used in an initial forming process. Additional voltage pulses having amplitudes that are less than the amplitude of the reform voltage pulse may be subsequently applied. By applying a reform voltage pulse in the middle of, or at the end of, a memory set sequence including multiple voltage pulses, a resistive memory device may have a larger memory window and improved data retention relative to resistive memory devices programmed using conventional programming methods.

  • Patent number: 11682457
    Abstract: A resistive random access memory (RRAM) circuit and related method limits current, or ramp voltage, applied to a source line or bitline of an RRAM array. The RRAM array has one or more source lines and one or more bitlines. A control circuit sets an RRAM cell to a low resistance state in a set operation, and resets the RRAM cell to a high resistance state in a reset operation. A voltage applied to a bitline or source line is ramped during a first time interval, held to a maximum voltage value during a second interval, and ceased after the second time interval.
