Abstract: Described apparatuses and methods relate to erroneous select die access (SDA) detection for a memory system. A memory system may include a memory controller and a memory device that are capable of implementing an SDA protocol that enables selective memory die access to multiple memory devices that couple to a command bus. A memory device can include logic that determines if signaling that conflicts with the SDA protocol is detected. If it is determined that conflicting signaling is detected, the logic may provide an indication of the conflicted signaling. In doing so, the erroneous SDA detection described herein may reduce the likelihood of a memory device erroneously masking memory dice, thereby limiting the memory device from exhibiting unexpected, and in some cases, dangerous behavior.

Abstract: An energy-efficient and area-efficient, mitigation of errors in a memory media device that are caused by row hammer attacks and the like is described. The detection of errors is deterministically performed while maintaining, in an SRAM, a number of row access counters that is smaller than the total number of rows protected in the memory media device. The reduction of the number of required counters is achieved by aliasing a plurality of rows that are being protected to each counter. The mitigation may be implemented on a per-bank basis, per-channel basis or per-memory media device basis. The memory media device may be DRAM.

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.

Abstract: Apparatuses and techniques for controlling usage-based disturbance mitigation are described. In an example aspect, usage-based disturbance mitigation is performed between activation and precharging of a row. More specifically, usage-based disturbance circuitry performs an array counter update procedure while the row is active. The techniques for controlling usage-based disturbance mitigation control timing of the array counter update procedure at a multi-bank level or a local-bank level. Additionally, the techniques for controlling usage-based disturbance mitigation control a timing of a precharging operation to ensure completion of the array counter update procedure. The techniques for controlling usage-based disturbance mitigation are not limited to the array counter update procedure and can generally be applied to other aspects of usage-based disturbance mitigation, such as bit-error detection and/or correction.

The second die may implement counters to track quantities of access operations associated with respective rows of memory cells of the second die. The second interface block may transmit alert signaling to the first interface block based on a value of a counter, and the first interface block may evaluate the alert signaling and transmit refresh signaling to the second interface block to perform one or more refresh operations.
