Publication number: 20250111872Abstract: Apparatuses, systems, and methods for refresh rate register adjustment based on a targeted refresh queue. A memory includes a temperature sensor which measures a temperature of the memory. The memory also includes a targeted refresh queue which stores identified aggressor addresses. A value of a refresh rate register is set based on both the measured temperature and the number of addresses in the queue. A controller of the memory reads the value of the refresh rate register and provides a refresh signal with timing based on the refresh rate register. In some embodiments, a ratio of targeted and normal refresh operations is adjusted based on how many addresses are in the targeted refresh queue.Type: ApplicationFiled: June 19, 2024Publication date: April 3, 2025Applicant: MICRON TECHNOLOGY, INC.Inventors: Wonjun Choi, Hyun Yoo Lee

Patent number: 12235783Abstract: Described apparatuses and methods facilitate bus training with multiple dice, such as multiple memory dice. A controller can communicate with multiple dice over a bus to perform bus training by sending a test pattern and receiving in return a feedback pattern indicative of the bits detected by the dice. Because suitable signal timing can differ between dice, even those using the same bus, the controller may attempt to train each die separately from the others. In some situations, however, individualized training may be infeasible. To accommodate such situations, logic associated with two or more dice can combine the bits as detected from the test pattern into a combined feedback pattern. A timing parameter that is jointly suitable for multiple dice can be determined, and the bus training may be concluded, responsive to the combined feedback pattern matching the test pattern. The multiple dice may be stacked or linked.Type: GrantFiled: August 30, 2022Date of Patent: February 25, 2025Assignee: Micron Technology, Inc.Inventors: Francesco Douglas Verna-Ketel, Hyun Yoo Lee, Smruti Subhash Jhaveri, John Christopher Sancon, Yang Lu, Kang-Yong Kim

Because suitable signal timing can differ between dice, even those using the same bus, a controller may train each die separately from the others. In some situations, however, individualized training may be infeasible. To accommodate such situations, logic associated with two or more dice can combine, using at least one logical operation, bits as detected from the test pattern into a combined feedback pattern. A timing parameter that is jointly suitable for multiple dice can be determined, and the bus training may be concluded, responsive to the combined feedback pattern matching the test pattern. The multiple dice may be stacked or linked.Type: GrantFiled: August 30, 2022Date of Patent: February 25, 2025Assignee: Micron Technology, Inc.Inventors: Yang Lu, Creston M.

Patent number: 12223995Abstract: Described apparatuses and methods relate to adaptive memory registers for a memory system that may support a nondeterministic protocol. To help manage power-delivery networks in a memory system, a device includes logic that can write values to memory registers associated with memory blocks of a memory array. The values indicate whether an associated memory block has been refreshed within a refresh interval. Other logic can read the registers to determine whether a block has been refreshed. The device also includes logic that can access data indicating a row address that was most recently, or is next to be, refreshed and write values representing the address to another register. The register can be read by other logic to determine whether a wordline potentially affected by an activation-based disturb event is near to being refreshed. These techniques can reduce the number of refresh operations performed, saving power and reducing costs.Type: GrantFiled: August 30, 2022Date of Patent: February 11, 2025Assignee: Micron Technology, Inc.Inventors: John Christopher Sancon, Kang-Yong Kim, Yang Lu, Hyun Yoo Lee

Publication number: 20250004875Abstract: Described apparatuses and methods provide configurable error correction code (ECC) circuitry and schemes that can utilize a shared ECC engine between multiple memory banks of a memory, including a low-power double data rate (LPDDR) memory. A memory device may include one or more dies with multiple memory banks. The configurable ECC circuitry can use an ECC engine that services a memory bank by producing ECC values based on data stored in the memory bank when data-masking functionality is enabled. When data-masking functionality is disabled, the configurable ECC circuitry can use the shared ECC engine that services at least two memory banks by producing ECC values with a larger quantity of bits based on respective data stored in the at least two memory banks. By using the shared ECC engine responsive to the data-masking functionality being disabled, the ECC functionality can provide higher data reliability with lower die area utilization.Type: ApplicationFiled: September 10, 2024Publication date: January 2, 2025Applicant: Micron Technology, Inc.Inventors: Keun Soo Song, Kang-Yong Kim, Hyun Yoo Lee

Patent number: 12176061Abstract: Described apparatuses and methods enable communication between a host device and a memory device to establish relative delays between different data lines. If data signals propagate along a bus with the same timing, simultaneous switching output (SSO) and crosstalk can adversely impact channel timing budget parameters. An example system includes an interconnect having multiple data lines that couple the host device to the memory device. In example operations, the host device can transmit to the memory device a command indicative of a phase offset between two or more data lines of the multiple data lines. The memory device can implement the command by transmitting or receiving signals via the interconnect with different relative phase offsets between data lines. The host device (e.g., a memory controller) can determine appropriate offsets for a given apparatus. Lengths of the offsets can vary. Further, a system can activate the phase offsets based on frequency.Type: GrantFiled: January 23, 2024Date of Patent: December 24, 2024Assignee: Micron Technology, Inc.Inventors: Kang-Yong Kim, Hyun Yoo Lee, Timothy M.
