N-type dopants for efficient solar cells
Triazabicylodecene can effectively n-dope a variety of organic semiconductors, including PCBM, thus increasing in-plane conductivities. We synthesized a series of TBD-based n-dopants via an N-alkylation reaction and studied the effect of various alkyl chains on the physical and device properties of the dopants. Combining two TBD moieties on a long alky chain gave a solid dopant, 2TBD-C10, with high thermal stability above 250° C. PCBM films doped by 2TBD-C10 were the most tolerant to thermal annealing and reached in-plane conductivities of 6.5×10−2 S/cm. Furthermore, incorporating 2TBD-C10 doped PCBM as the electron transport layer (ETL) in methylammonium lead triiodide (MAPbI3) based photovoltaics led to a 23% increase in performance, from 11.8% to 14.5% PCE. |

Systems and methods for streaming storage device content
A method of streaming between a storage device and a secondary device includes receiving, by the storage device, from the secondary device, a memory read request command including a memory address of the storage device corresponding to a stream identity, the stream identity being unique between the storage device and the secondary device; streaming, by the storage device, data between the storage device and the secondary device by transferring the data corresponding to the memory address of the storage device to the secondary device; determining, by the storage device, that the data requested by the secondary device in the memory read request command is transferred to the secondary device; and ending, by the storage device, the streaming between the storage device and the secondary device. |

Memory tiering using PCIe connected far memory
A processing device in a host system monitors a data temperature of a plurality of memory pages stored in a host-addressable region of a cache memory component operatively coupled with the host system. The processing device determines that a first memory page of the plurality of memory pages satisfies a first threshold criterion pertaining to the data temperature of the first memory page and sends a first migration command indicating the first memory page to a direct memory access (DMA) engine executing on a memory-mapped storage component operatively coupled with the cache memory component and with the memory-mapped storage component via a peripheral component interconnect express (PCIe) bus. The first migration command causes the DMA engine to initiate a first DMA transfer of the first memory page from the cache memory component to a host-addressable region of the memory-mapped storage component. |

Managing prefetch lookahead distance based on memory access latency
Memory prefetching in a processor comprises: identifying, in response to memory access instructions, a pattern of addresses; in response to a first memory access request corresponding to a sub-pattern of the pattern of addresses, prefetching a first address that is offset from the sub-pattern of addresses by a first lookahead value, wherein the first address is part of the pattern; measuring a memory access latency; determining, based on the memory access latency, a second lookahead value, wherein the second lookahead value is different from the first lookahead value; and in response to a second memory access request corresponding to the sub-pattern of the pattern of addresses, prefetching a second address, wherein the second address is part of the pattern, and wherein the second address is offset from the sub-pattern of addresses by the second lookahead value. |

System and methods for reducing global coherence unit snoop filter lookup via local memories
In a multi-node system, each node includes tiles. Each tile includes a cache controller, a local cache, and a snoop filter cache (SFC). The cache controller responsive to a memory access request by the tile checks the local cache to determine whether the data associated with the request has been cached by the local cache of the tile. The cached data from the local cache is returned responsive to a cache-hit. The SFC is checked to determine whether any other tile of a remote node has cached the data associated with the memory access request. If it is determined that the data has been cached by another tile of a remote node and if there is a cache-miss by the local cache, then the memory access request is transmitted to the global coherency unit (GCU) and the snoop filter to fetch the cached data. Otherwise an interconnected memory is accessed. |

Systems and methods for dynamic in-memory caching of mappings into partitions
Systems and methods for routing requests to dynamically cached mappings are disclosed. A system may comprise a memory storing instructions and at least one processor configured to execute instructions to perform operations including: receiving an access request to access first item data from a user device, the access request having an access key; based on the access key, routing the request to a server having an in-memory cache with multiple partitions associated with different access key types and storing the first item data and second item data; receiving, from the server, the first item data; and transmitting the first item data to the user device. |
