Abstract: Controlling an optical phased array includes applying optical phase shifts by an array of phase shifter (PS) elements, each PS element applying an optical phase shift based on an input voltage signal applied across first and second terminals of the PS element, providing output voltage signals from an array of driver elements. During a charging time period, each driver element provides an output voltage signal to determine a corresponding input voltage signal applied across at least one of the PS elements; an array of switches control connectivity between the driver elements and respective PS elements; and all of the second terminals of all of the PS elements in the array of PS elements are maintained at a common voltage. The total number of switches in the array of switches is at least as large as the total number of PS elements in the array of PS elements.

The functional circuitry comprises at least one output and a state of the output depends on the logical operations. Domain control circuitry controls the control domain to put the functional circuitry in one of the operational state and a non-operational state.

Self-test control circuitry causes the domain control circuitry to control the control domain to put the functional circuitry in the non-operational state and to cause a self-test procedure to be carried out with respect to the functional circuitry.

Abstract: Methods, systems, and devices for input/output line sharing for memory subarrays are described. I/O lines may be shared across subarrays, which may correspond to separate memory tiles. The sharing of I/O lines may allow an I/O line to carry data from one subarray in response to access commands associated with one address range, and to carry data from another subarray in response to access commands associated with another address range. In some cases, sense amplifiers and other components may also be shared across subarrays, including across subarrays in different banks. The sharing of I/O lines may, in some cases, support activating only a subset of subarrays in a bank when accessing data stored in the bank, which may provide power savings.
