  • Patent number: 11928039
    Abstract: Apparatuses and techniques for implementing a data-transfer test mode are described. The data-transfer test mode refers to a mode in which the transfer of data from an interface die to a linked die can be tested prior to connecting the interface die to the linked die. In particular, the data-transfer test mode enables the interface die to perform aspects of a write operation and output a portion of write data that is intended for the linked die. With the data-transfer test mode, testing (or debugging) of the interface die can be performed during an earlier stage in the manufacturing process before integrating the interface die into an interconnected die architecture. For example, this type of testing can be performed at a wafer level or at a single-die-package (SDP) level. In general, the data-transfer test mode can be executed independent of whether the interface die is connected to the linked die.

  • Publication number: 20240079036
    Abstract: Apparatuses and techniques for implementing a standalone mode are described. The standalone mode refers to a mode in which a die that is designed to operate as one of multiple dies that are interconnected can operate independently of another one of the multiple dies. Prior to connecting the die to the other die, the die can perform a standalone read operation and/or a standalone write operation in accordance with the standalone mode. In this way, testing (or debugging) can be performed during an earlier stage in the manufacturing process before integrating the die into an interconnected die architecture. For example, this type of testing can be performed at a wafer level or at a single-die-package (SDP) level. In general, the standalone mode can be executed independent of whether the die is connected to the other die.

  • Publication number: 20240078041
    Abstract: This document describes apparatuses and techniques for die-based rank management for a memory system. In various aspects, a die-based rank controller (controller) can determine which memory dies of a memory device are not functional to store data and correlate rank selections of a memory system to ranks of other memory dies (e.g., functional memory dies). The controller may store information that indicates the correlation or mapping of the rank selections to the ranks of the other memory dies to enable access to those ranks of the memory system. In some aspects, the controller receives a command to access the memory device with a rank selection, and the controller enables access to a corresponding rank based on the information. By so doing, aspects of die-based rank management enable memory packages with non-functional memory dies to be used instead of discarded, which can increase production utilization or lower manufacturing costs.

  • Publication number: 20240071464
    Abstract: Described apparatuses and methods enable a system including at least one memory device to load different address scramble patterns on dies of the memory device. The address scramble patterns may include the logical-to-physical conversion of rows in the memory device or the memory dies. In aspects, the apparatuses and methods can change the address scrambles at different intervals, such as after a power reset or when the data stored on the memory device is invalid, not current, flushable, or erasable. The described aspects may reduce effectiveness of usage-based disturb attacks used by malicious actors to discover a layout of a type of particular memory device or memory die.

  • Publication number: 20240071461
    Abstract: 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.

  • Publication number: 20240070102
    Abstract: Described apparatuses and methods facilitate bus training with multiple dice, such as multiple memory dice. A controller can communicate with multiple dice 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, 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.

  • Publication number: 20240070101
    Abstract: 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.

  • Publication number: 20240071437
    Abstract: Described apparatuses and methods relate to selectively disabling a die that may be included in a multiple-die package without necessarily disabling all the remaining dies within the package. A nonvolatile circuit, such as one or more fuses, may be included within individual dies and/or otherwise incorporated within the package. The nonvolatile circuit maintains a value for the die that is indicative of the operability of the die. Die disablement logic is operatively coupled to the nonvolatile circuit and can disable the die based on the value indicating that the die is unusable. The disabling of the die by the die disablement logic may be controlled by an override signal that allows the disabling or prevents the logic from disabling the die. Thus, the die disablement logic can prevent a defective die from functioning, but the die disablement logic may be overridden for testing or debugging.
