Patent ID: 11942404
Assignee: MICRON TECHNOLOGY, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. An apparatus, comprising:
a device substrate comprising semiconductor material and bond pads coupled with an active surface of the device substrate,
a package substrate secured to the device substrate, the package substrate configured to route signals to and from the bond pads, and
a ball grid array supported on, and electrically connected to, the package substrate, the ball grid array comprising an odd number of columns, such that the ball grid array comprises a central column having equal numbers of other columns on opposite sides of the central column,
wherein each ball of the ball grid array positioned and configured to carry a clock signal or a strobe signal is located in the central column of the ball grid array,
wherein a number of the balls of the ball grid array positioned and configured to carry a data signal is between about one-eighth and about one-fourth a number of the balls of the ball grid array positioned and configured to carry a voltage or connect to ground;
wherein a number of the balls of the ball grid array positioned and configured to carry a data signal is between about two-fifths about nine-tenths a number of the balls of the ball grid array positioned and configured to connect to input/output memory supply voltage.
