Publication number: 20240078173Abstract: A training operation may be performed by a memory controller to provide a system clock signal and a data clock signal having a desired temporal (e.g., phase) relationship to one another. The system clock and data clock signals may be provided to a memory. In some examples, the memory controller may provide a command to the memory to put the memory in a training mode. Once in the training mode, the memory controller may provide a write command and toggle the data clock signal a number of times. If the memory provides one output, the memory controller may adjust the relationship between the data clock and system clock signals. If the memory provides another output, the memory controller may maintain the relationship between the data clock and system clock signals and exit the training mode.Type: ApplicationFiled: July 17, 2023Publication date: March 7, 2024Applicant: MICRON TECHNOLOGY, INC.Inventors: OSAMU NAGASHIMA, YOSHINORI MATSUI, KEUN SOO SONG, HIROKI TAKAHASHI, SHUNICHI SAITO

Patent number: 11914874Abstract: Methods, systems, and apparatuses related to memory operation with multiple sets of latencies are disclosed. A memory device or system that includes a memory device may be operable with one or several sets of latencies (e.g., read, write, or write recovery latencies), and the memory device or system may apply a set of latencies depending on which features of the memory device are enabled. For example, control circuitry may be configured to enable one or more features during operations on a memory array, and the control circuitry may apply a set of latency values based on a number or type of features that are enabled. The sets of latency values may depend, for example, on whether various control features (e.g., dynamic voltage frequency scaling) are enabled, and a device may operate within certain frequency ranges irrespective of other characteristics (e.g., mode register values) or latencies applied.Type: GrantFiled: August 2, 2021Date of Patent: February 27, 2024Inventors: Dean D. Gans, Yoshiro Riho, Shunichi Saito, Osamu Nagashima

Publication number: 20240038289Abstract: A clock generator circuit may generate internal data clock signals, such as quadrature phase clock signals, based at least in part, on one clock signal responsive, at least in part, to another clock signal. In some examples, the internal data clock signals may be generated from a system clock signal responsive to a data clock signal. In some examples, the internal data clock signal may be generated by sampling the system clock signal. In some examples, the sampling may be performed responsive to the data clock signal. In some examples, a latch may latch a state of the system clock signal responsive to the data clock signal. The latch may output the internal data clock signal.Type: ApplicationFiled: July 17, 2023Publication date: February 1, 2024Applicant: MICRON TECHNOLOGY, INC.Inventors: Osamu NAGASHIMA, Yoshinori MATSUI, Keun Soo SONG, Hiroki TAKAHASHI, Shunichi SAITO

Patent number: 10289316Abstract: A monitoring unit obtains the performance information of each of a plurality of volumes included in a storage device. A setting unit obtains a performance target value for each of one or more targeted volumes from among the plurality of volumes. Based on the performance information obtained by the monitoring unit and based on a first-type standby time that is attributed to bandwidth limitation of IO requests with respect to the targeted volumes which are obtained by the setting unit and which achieve the performance target value, a bandwidth managing unit obtains the bandwidth for the targeted volumes that achieve the performance target value and performs bandwidth limitation to change the bandwidth of the targeted volumes to the obtained bandwidth.Type: GrantFiled: August 24, 2017Date of Patent: May 14, 2019Assignee: FUJITSU LIMITEDInventors: Takeshi Nagata, Yuto Kojima, Osamu Nagashima
