Abstract: Methods and systems for exposing a desired shape in an area on a surface using a charged particle beam system include determining a local pattern density for the area, based on an original set of exposure information. A pre-proximity effect correction (PEC) maximum dose for the local pattern density is determined, based on a pre-determined target post-PEC maximum dose. The pre-PEC maximum dose may be calculated near an edge of the desired shape. Methods also include modifying the original set of exposure information with the pre-PEC maximum dose to create a modified set of exposure information.

Abstract: Self-Addressing Dynamic Random Access Memory (SADRAM) includes Dynamic Random Access Memory (DRAM) and a logic layer having direct access to the DRAM which provides symbolic addressing services. These services are provided by sequencers realized in the logic layer. The sequencers maintains a DRAM row or row-pair in sorted order, finds a location within the row or row-pair for a new data element, and inserts the new data element into the row or row-pair—all while preserving the sorted order. The sequencer is a plurality sequencer groups, each sequencer group is a plurality of sequencer cells. The sequencer cells to perform a highly parallel pipeline insertion of a new data element. The logic layer also defines a Self-Addressing Memory Central Processing Unit (SamPU) which is operatively coupled to the sequencer and configured to control the sequencer. The logic layer also provides program memory for SamPU and a memory cache in which is built an index database.

Abstract: Systems and techniques for laser transmitter characterization for accurate laser aging are described herein. A set of bias current-temperature pairs is collected for a laser diode. A bias current-temperature curve is calculated for the laser diode using the set of bias current-temperature pairs. A timestamp is assigned to the bias current-temperature curve. The bias current-temperature curve and the timestamp are stored in a non-volatile memory device communicatively coupled to a laser device that includes the laser diode. The bias current-temperature curve and the timestamp are transmitted to a cloud-based storage facility.

Abstract: Systems, apparatuses, and methods related to memory systems and operation are described. A memory system may be coupled to a processor, which includes a memory controller. The memory controller may determine whether targeting of first data and second data by the processor to perform an operation results in processor-side cache misses. When targeting of the first data and the second data result in processor-side cache misses, the memory controller may determine a single memory access request that requests return of both the first data and the second data and instruct the processor to output the single memory access request to a memory system via one or more data buses coupled between the processor and the memory system to enable processing circuitry implemented in the processor to perform the operation based at least in part on the first data and the second data when returned from the memory system.

Abstract: A method for exposing a pattern in an area on a surface using a charged particle beam lithography is disclosed and includes inputting an original set of exposure information for the area. The area comprises a plurality of pixels, and the original set of exposure information comprises dosages for the plurality of pixels in the area.

Abstract: Methods, apparatuses, and systems related to mapping a virtual address using a physical address are described. In a memory system including a memory (e.g., cache) and a content addressable memory (CAM), the CAM can be configured to search data requested by a host from the memory based on multiple indicators stored in the CAM. For example, in the event that the data stored in the memory is not searchable based on a particular indicator such as a virtual address of a memory array (e.g., main memory), the CAM be configured to search the data based on another indicator such as a physical address of the memory array. Searching the data based on multiple indicators can resolve a synonym problem.
