    摘要： According to one implementation of the present disclosure, a memory array to block read-access of uninitialized memory locations is disclosed. The memory array includes: a plurality of memory cells apportioned into a plurality of memory columns and a plurality of memory rows, where each of the memory cells is configured to store a single bit of memory data; and one or more initialization columns corresponding to at least one of the plurality of memory columns. The initialization state of a memory row of the memory cells may be configured to be stored in: the memory row; a latch of word-line driver circuitry coupled to the memory array; or a memory cell of the one or more initialization columns of a corresponding row of the plurality of memory rows of the memory array.

    摘要： A chip-carrier package includes a data processing system having one or more slave dies, a master die and a system bus. Each slave die includes a slave device and a slave-side wireless bus interface (WBI) coupled to the slave device. The master die includes a master device, one or more bus-side WBIs coupled to the master device. Each bus-side WBI is configured to be wirelessly coupled to at least one slave-side WBI of the one or more slave dies and a system bus. The system bus includes the one or more bus-side WBIs and the slave-side WBIs of the one or more slave-side dies. The system bus is configured to exchange information between the master device and the slave devices of the one or more slave dies.

    摘要： A method, system and surface covering for enabling wireless detection of damage to a structure is disclosed. At least one array having a plurality of nodes are coupled to a surface covering, such as at least one of a wall, ceiling and floor covering for a least a portion of the structure. An electronic reader is operable to wirelessly interrogate the array and read return signals from nodes in the array. The return signals contain data representing an ID for corresponding responsive nodes in the array, and the returned IDs are extracted and compared to a plurality of IDs stored in a data store for nodes in any given array. A mismatch between the returned and stored IDs for the nodes in the array indicates a structural defect in a respective portion of the structure overlaid by the floor/wall covering.

    摘要： A memory device and method of operating the memory device are provided. The memory device has bitcells arranged in a plurality of rows and columns. Row driver circuitry provides access to the array of bitcells by selection of an access row of the plurality of rows. The row driver circuitry comprises a retention control latch to store a retention control value and row power gating circuitry responsive to a retention signal to power gate at least one row when the retention control value has a first value and to leave the at least one row powered when the retention control value has a second value. Row-based retention of the content of the bit cells is thus provided, and the leakage current of the memory device when it is in a retention (e.g. sleep) mode, and only some of its rows contain valid data, can thus be reduced.

    摘要： Wearable items and methods of monitoring wearable items are disclosed. The wearable item comprises a flexible base material forming at least a portion of the wearable item, plural conductive traces traversing the flexible base material, and conductivity sensing circuitry coupled to the plural conductive traces. The conductivity sensing circuitry is configured to distinguish conductivity from non-conductivity of the plural conductive traces, and configured to generate a conductivity indication for at least one of the plural conductive traces. The plural conductive traces follow indirect paths across the flexible base material, allowing the flexible material to flex and stretch normally without breaking the conductive traces.
