Patent attributes
Methods, systems, and devices for variable filter capacitance are described. Within a memory device, voltages may be applied to access lines associated with two voltage sources to increase the capacitance provided by the access lines between the two voltage sources. In some cases, the access lines may be in electronic communication with capacitive cells that include a capacitive element and a selection component, and the voltage sources and access lines may be configured to utilize the capacitive elements and the capacitance between the access lines to generate an increase capacitance between the voltage sources. In some cases, decoders may be used to implement certain configurations that generate different capacitance levels. Similarly, sub-decoders may generate different capacitance levels by selecting portions of a capacitive array.
