Abstract: A high-speed, low-power memory device comprises an array of non-linear conductors wherein the storage, address decoding, and output detection are all accomplished with diodes or other non-linear conductors. In various embodiments, the row and column resistors are switchable between a high resistance when connected to a row or column that is non-selected, and a low resistance when connected to the selected row and column.

Abstract: One of the simplest forms of data storage devices is the diode array storage device. However, a problem with diode array storage devices is that as the size of the array increases, the number of non-addressed diodes connected between a given selected row or column of the array and the non-addressed columns or rows of the array, respectively, also becomes very large. While the leakage current through any one non-addressed diode on the selected row or column will have little impact on the operation of the device, the cumulative leakage through multiple thousands of non-addressed diodes can become significant. This aggregate leakage current can become great enough that the output voltage can be shifted such that the threshold for distinguishing between a one state and a zero state of the addressed diode location can become obscured and can result in a misreading of the addressed diode location. The present invention is a means to manage the leakage currents in a diode array storage device.

Abstract: The present invention is a method of applying a topographical surface to a part such as a substrate without the need for low temperature softening of that part while retaining high aspect ratios and densely packed features in that topography. A substrate, selected for its ability to be processed at a given desired temperature, has a layer of material applied to its surface. This layer is selected, among other reasons, for its ability to be molded. Typically, it is expected that the substrate will be able to withstand the higher temperatures of semiconductor post-processing whereas the applied layer will be moldable at low temperatures. This combination enables low cost embossing of a topography into this surface layer. The present invention comprises means to transfer this topography from the low temperature material into the higher temperature substrate.

Abstract: The scale of the devices in a diode array storage device, and their cost, are reduced by changing the semiconductor based diodes in the storage array to cold cathode, field emitter based devices. The field emitters and a field emitter array may be fabricated utilizing a topography-based lithographic technique.

Abstract: A read-only data storage and retrieval device is presented having no moving parts and requiring very low power. Addressing can be accomplished sequentially where the address increments automatically or can be accomplished randomly. High density storage is achieved through the use of a highly symmetric diode matrix that is addressed in both coordinate directions; its symmetry makes the Dual-addressed Rectifier Storage (DRS) Array very scaleable scalable, particularly when made as an integrated circuit. For even greater storage flexibility, multiple digital rectifier storage arrays can be incorporated into the device, one or more of which can be made removable and interchangeable.
