Embodiment Construction

[0022] Figure 1 illustrates the various operating principles of the preferred embodiment of the invention at a high level. Data is stored in a series of bistable (or more generally multistable) data cells 10a, 10b, 10c, 10d arranged in series so as to form a memory shift register 8 . Although the shift register 8 may in practice comprise 100, 1000, even 2500 or more such data units, only 4 data units are illustrated in FIG. 1 for clarity. Using a controller 14, data is written into one end of the memory shift register 8 through an input unit 20 (which may communicate with an electrode 22 whose position is controlled by an applied electric field); using the same controller, the data can be shifted from memory The other end of bit register 8 is read. Data cells 10a-10d interact with their neighboring data cells via electrostatic, magnetostatic, mechanical or hydrodynamic force (or a combination of these) to propagate data along register 8 synchronously. This propagation is ini...

Abstract

An electromechanical storage device includes an input element that facilitates the input of data, a series of data elements, and a terminating element that facilitates the reading out of data. The data elements each have at least two stable mechanical orientations, and these orientations can be utilized to store data. Data may be entered into the device by applying a transient electromagnetic pulse to the data elements. The device is constructed such that as a data bit is entered into the series of data elements, any data bits that have been previously entered into the series are shifted towards the terminating element.

Description

technical field [0001] This invention relates to a mechanical data storage device and, more particularly, to a memory shift register in which data bits are stored mechanically but input into the storage device using electromagnetic means. Background technique [0002] Hard drives are commonly used for data storage due to their relatively low cost per bit. But they are often subject to shocks - the entire disk drive can be wiped. For this reason: Creating reliable storage systems based on disk drive technology is complex and expensive. Other problems with disk drives include their enormous static power consumption and their inability to access data randomly and in parallel. [0003] Although many inexpensive solid-state storage solutions have been proposed, there is little hope of reducing the price of storage significantly below that of flash memory. Any such device would likely be fabricated by standard microelectronic fabrication techniques, and even if the memory layer...
