Abstract
Apparatuses and methods for input receiver circuits and receiver masks for electronic memory are disclosed. Embodiments of the disclosure include memory receiver masks having shapes other than rectangular shapes. For example, a receiver mask according to some embodiments of the disclosure may have a hexagonal shape. Other shapes of receiver masks may also be included in other embodiments of the disclosure. Circuits, timing, and operating parameters for achieving non-rectangular and various shapes of receiver mask are described.
Claims18
A method, comprising:
- providing a clock to a memory device;
- and
- providing an input signal to the memory device, wherein the input signal is outside a receiver mask defined as a hexagonal mask shape based, at least in part, on one or more voltage and timing parameters, wherein a center of the receiver mask is at a system clock cross point or the center is offset a time from a rising edge of a data clock.
An apparatus, comprising:
- a memory controller configured to provide a clock to a memory device on the clock bus and to provide an input signal to the memory device, wherein the input signal does not encroach a receiver mask for the input receiver, the receiver mask defined as a hexagonal mask shape based, at least in part, on one or more voltage and timing parameters, wherein the receiver mask is offset or center aligned from a rising edge of the clock.
An apparatus, comprising:
- a memory including an input receiver;
- a command/address bus;
- a data bus;
- a clock bus;
- and
- a memory controller coupled to the memory through the command/address bus, the data bus, and the clock bus, the memory controller configured to provide a clock to a memory device on the clock bus and to provide an input signal to the memory device, wherein the input signal does not encroach a receiver mask for the input receiver, the receiver mask defined as a hexagonal mask shape based, at least in part, on one or more voltage and timing parameters, wherein a center of the receiver mask is at a system clock cross point or the center is offset a time from a rising edge of a data clock.
