Publication number: 20250208963Abstract: In some implementations, a device may cause a single host device to load data to a first memory device of a plurality of memory devices configured in a fabric. The device may cause the first memory device to propagate the data to one or more second memory devices, of the plurality of memory devices, via one or more peer-to-peer transfer operations to replicate the data from the first memory device to the one or more second memory devices without involvement of the single host device.Type: ApplicationFiled: November 20, 2024Publication date: June 26, 2025Inventors: Michael R. SPICA, Thomas T. TANGELDER

Publication number: 20250173302Abstract: In some implementations, a control unit component of a compute express link (CXL) compliant memory device may transmit, to a generator component of the CXL compliant memory device, an indication of a type of test being performed for the CXL compliant memory device. The generator component may generate a set of instructions based on the type of test being performed for the CXL compliant memory device. The generator component may inject the set of instructions into a data path of the CXL compliant memory device. The control unit component and/or a comparator component of the CXL compliant memory device may extract a set of data from the data path, wherein the set of data is generated by the data path based on the set of instructions. The control unit component may determine a test result based on the set of data.Type: ApplicationFiled: November 22, 2024Publication date: May 29, 2025Inventor: Michael R. SPICA

Patent number: 12142336Abstract: A detection is made by a processing device allocated to a memory device test board of a distributed test platform that a memory sub-system has engaged with a memory device test resource of the memory device test board. A test is identified to be performed for a memory device of the memory sub-system. The test includes first instructions to be executed by a memory sub-system controller of the memory sub-system in performance of the test and second instructions to be executed by the processing device in performance of the test. The second instructions are to cause one or more test condition components of the memory device test resource to generate one or more test conditions to be applied to the memory device while the memory sub-system executes the first instructions. Responsive to a transmission of the first instructions to the memory sub-system controller, the second instructions are executed.Type: GrantFiled: April 8, 2022Date of Patent: November 12, 2024Assignee: Micron Technology, Inc.Inventors: Gary D. Hamor, Michael R. Spica, Donald Shepard, Patrick Caraher, João Elmiro da Rocha Chaves

Patent number: 12013734Abstract: A system receives event information associated with an event that corresponds to a temperature of a memory sub-system including memory devices encased in respective packages. The system determines whether the event information associated with the event satisfies a threshold condition. Responsive to determining that the event information associated with the event satisfies the threshold condition, the system causes a thermoelectric component (TEC) that is coupled to an external surface of each of the respective packages of the memory devices of the memory sub-system to transfer thermal energy between the TEC and the memory devices via thermal conduction.Type: GrantFiled: August 9, 2022Date of Patent: June 18, 2024Assignee: Micron Technology, Inc.Inventor: Michael R. Spica

Patent number: 11960349Abstract: A memory sub-system comprises a power management component comprising a plurality of regulators configured to supply respective operating voltages for components of the memory sub-system. The power management component is configured to adjust a regulator voltage level provided to a particular component until an operation state change of the particular component is detected. The power management voltage level is further configured to determine a value of the regulator voltage level at which the operation state change of the particular component is detected.Type: GrantFiled: October 7, 2022Date of Patent: April 16, 2024Assignee: Micron Technology, Inc.Inventors: Michael R. Spica, Patrick T. Caraher

Patent number: 11416048Abstract: First event information that is associated with an event that corresponds to a temperature of a memory sub-system is received. Whether the first event information associated with the event that corresponds to the temperature of the memory sub-system satisfies a first threshold condition is determined. Responsive to determining that the first event information associated with the event that corresponds to the temperature of the memory sub-system satisfies the first threshold condition, a thermoelectric component (TEC) is caused to change from an inactive state to an active state by decreasing a temperature at a bottom surface of the TEC that is coupled to the memory sub-system as a temperature at a top surface of the TEC increases.Type: GrantFiled: July 22, 2019Date of Patent: August 16, 2022Assignee: Micron Technology, Inc.Inventor: Michael R.
