Abstract
In an example, an apparatus includes a memory array in a first region and decode circuitry in a second region separate from a semiconductor. The decode circuitry is coupled to an access line in the memory array.
Claims20
A method, comprising:
- forming a memory array in a first region;
- forming a conductor coupled to an access line of the memory array;
- forming a trigger device in a second region and coupled to the conductor;
- and
- forming a switch device in the second region and coupled to the conductor, wherein the trigger device and the switch device are configured to couple the memory array to a global decode node via the conductor;
- activating the trigger device to decode an address line and activate the switch device utilizing a threshold current.
