Abstract: Methods, systems, and devices for row hammer mitigation for stacked memory architectures are described. A semiconductor system, such as a memory system, may distribute operations for row hammer mitigation across circuitry of the semiconductor system. A first interface block of a first die of the semiconductor system may exchange signaling with a second interface block of a second die of the semiconductor system to perform row hammer mitigation operations. 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.

Abstract: Methods, systems, and devices for row hammer mitigation reliability in stacked memory architectures are described. A spare counter may be implemented at a first interface block of a logic die to enable increased reliability and efficiency in row hammer mitigation. The first interface block may use a spare counter in case of an error associated with a counter at a memory array die. A second interface block of an array die may identify an error associated with a counter of a memory array and may transmit an indication of the error to the first interface block. The first interface block may receive the indication and may activate a spare counter to track access operations on (e.g., activations of) the row based on the indication. The first interface block may use the spare counter to evaluate whether to transmit refresh signaling to the second interface block for row hammer mitigation.

Abstract: Methods, systems, and devices for interface techniques for stacked memory architectures are described. A semiconductor system, such as a memory system, may distribute memory access circuitry among multiple semiconductor dies of a stack. A first die of the system may include logic circuitry operable to configure a set of multiple first interface blocks of the first die. Each first interface block may include circuitry operable to communicate with one or more second interface blocks of one or more second dies of the system to access a respective set of one or more memory arrays of the one or more second dies. In some examples, the system may include a respective controller for each first interface block to support access operations via the first interface block. The system may also include non-volatile storage, one or more sensors, or a combination thereof to support various operations of the system.

Abstract: Methods, systems, and devices for an interface layout for stacked memory architectures are described. A memory interface block may interface a plurality of memory dies to a host controller. The memory interface block may include an interface block coupled with multiple memory dies, which may be stacked on the memory interface block using through-silicon-vias. The memory interface block may include controllers, datapath blocks, and interface blocks associated with each memory die. As such, the memory interface block may perform functions such as queueing, ECC, and performing row repair and column repair procedures. In some examples, a layout for the memory interface block may include pairing controllers for at least two memory devices, such that a pair of controllers may share a command port to a pair of memory dies. Further, the memory interface block may include interfaces to the host controller that are different from the interface to each memory die.

Abstract: Methods, systems, and devices for schedule memory are described. Specifically, techniques are described for a memory interface between a host system and memory (e.g., a tightly coupled memory). For example, a memory interface block (MIB) between the host system and the memory system may schedule access operations performed by the memory system, schedule and perform error control operations, schedule and perform media management operations, as well as schedule and perform other operations. The use of such a MIB may enable the improvement of the memory system by reducing latency and increasing efficiency of memory accesses, while reducing impacts on the architecture and design of the host system.

Abstract: An apparatus can include first circuitry coupled to a FIFO memory. The first circuitry can provide a write pointer of the FIFO memory at a first rate. Second circuitry can be coupled to the FIFO memory. The second circuitry can provide a read pointer of the FIFO memory at a second rate that is different from the first rate. Third circuitry can be coupled to the first and second circuitries. The third circuitry can provide an indication of an error condition of the FIFO memory based on the write pointer and the read pointer.

Abstract: An anti-oxidation frying device includes a frying vessel having an electrically conductive body configured to heat cooking oil carried therein by a heating unit. A removable basket, also formed of electrically conductive material, is configured to be carried within the frying vessel to enable the cooking of food in the heated oil. A rectification circuit is coupled to the heating unit, the body of the frying vessel, and the basket. During operation the rectification circuit converts AC power from an external power source into a rippled, rectified AC current signal that is supplied to the heating unit, body of the frying vessel, and the basket, so as to create a reducing environment of available electrons for absorption by the cooking oil and food as it is prepared, thus extending the life of the cooking oil.

Abstract: A tension adjusting device is attached to an axle member of a driven wheel of a vehicle and is coupled to a forked frame member to adjust tension of a chain. The tension adjusting device has two tension adjusters joined to each side of the axle member that engages a guide recess of the forks of the frame member and support the axle fastener to secure the axle member to the two adjustment plates. The two adjustment plates include extending members that each extend over an end of each fork. An adjustment bore is drilled through the extending member and aligned with the ends of the forks. An adjustment stud is affixed through the adjustment bores to make contact with the end of the forks and to allow the axle member of the driven wheel to move in an adjustment slot to adjust the tension of the chain.
