Abstract

Configuring a ground plane to surround completely the individual magnetic storage elements and conductors of a memory array provides a durable package with excellent electrical properties. Mounting a ground plane in close proximity to the conductors of a magnetic storage array enhances the transmission line characteristics of the array conductors. The ground plane provides a distributive capacitance which offsets the inductance of the conductors and thus reduces their characteristic impedance. Configuring the ground plane so as to surround as completely as possible the individual storage elements and individual conductors provides the required capacitance and a protective package.

Configured Ground Plane

Configuring a ground plane to surround completely the individual magnetic storage elements and conductors of a memory array provides a durable package with excellent electrical properties. Mounting a ground plane in close proximity to the conductors of a magnetic storage array enhances the transmission line characteristics of the array conductors. The ground plane provides a distributive capacitance which offsets the inductance of the conductors and thus reduces their characteristic impedance. Configuring the ground plane so as to surround as completely as possible the individual storage elements and individual conductors provides the required capacitance and a protective package.

The drawing shows a storage device and a ground plane structure for completely enclosing the storage device. The ground plane is configured in matching parts 1 and 2 of anodized aluminum which, when placed together leave channels for the storage elements 3 and the array conductors 4. Parts 1 and 2 are configured as ramps for manufacture by coining or other facing techniques. The ramps of part 1 mate with the oppositely facing ramps of part 2 to make a sturdy structure having the required channels for the storage elements. Reliefs cut out of the ramps provide the required channels for conductors 4.

The ground plane structure can also be configured as a rectangularly channeled base block. Channels are milled out for holding the storage elements. Other channels are...
