    Abstract: A memory system includes an address mapping circuit. The address mapping circuit receives an input memory address having a first set of address bits. The address mapping circuit applies a logic function to the input memory address to generate a mapped memory address. The logic function uses at least a subset of the first set of address bits in two separate operations that respectively determine two portions of the mapped memory address.

    Abstract: A method of refreshing a memory is disclosed. The method includes accessing from active memory an active memory map. The active memory map is generated by software and identifies addresses corresponding to the active memory and associated refresh criteria for the addresses. The refresh criteria are evaluated for a portion of the active memory, and an operation initiated to refresh a portion of the active memory is based on the refresh criteria.

    Abstract: A sensing device projects near-field spatial modulations onto a closely spaced photodetector array. Due to physical properties of the grating, the point-spread response distributes spatial modulations over a relatively large area on the array. The spatial modulations are captured by the array, and photographs and other image information can be extracted from the resultant data. An image-change detector incorporating such a sensing device uses very little power because only a small number of active pixels are required to cover a visual field.
