Engineering Contradiction Analysis
1Adaptability or versatility
If traditional binary memory systems are used with two-state bit position constraint, then the system maintains simplicity and compatibility with existing frameworks, but memory requirements grow exponentially for complex computations, surpassing current technological capabilities
Solution Approach 1:
The patent changes the fundamental parameter of memory cell state from binary (2 states) to tri-state (3 states). Each memory cell can store one of three values: 0 (no charge), 1 (positive charge), or -1 (negative charge). This parameter change allows the system to store more information per cell and perform complex computations with fewer memory resources, directly addressing the exponential growth problem of binary systems.
Solution Approach 2:
The tri-state memory cell serves multiple functions: it can store data (0, 1, or -1), perform arithmetic operations (addition, subtraction, multiplication), and execute logical operations all within the same physical structure. This multi-functionality eliminates the need for separate computational and storage units, reducing overall system complexity and memory requirements for complex computations.
2Quantity of substance
If bidirectional memory system with three-state storage is implemented, then memory requirements are reduced and computational efficiency is improved, but the device complexity increases compared to traditional DRAM structures
Solution Approach 1:
The patent merges the storage function and the bidirectional control function into a single memory cell structure. The capacitor can be charged in both positive and negative directions, combining what would traditionally require separate positive-only charging circuits and negative-only charging circuits into one unified structure. This merging reduces the overall device complexity despite the increased functionality.
Solution Approach 2:
Instead of using two separate memory cells (one for positive charge, one for negative charge) to represent three states, the patent inverts the approach by using a single capacitor that can be charged in both directions. The inversion of the traditional unidirectional charging approach allows the system to achieve tri-state storage with fewer physical components, reducing device complexity.
3Adaptability or versatility
If single bit storage per memory cell is used, then the memory system operates within established binary frameworks, but the computing abilities are limited when solving problems requiring exponential variables
Solution Approach 1:
The patent changes the information density parameter from 1 bit per cell to 1.585 bits per cell (log2(3)). This parameter change allows the system to represent more complex computational states within the same physical footprint, enabling the solving of problems that require exponential variables without increasing physical memory requirements.
Solution Approach 2:
The patent adds a new dimension to memory storage by introducing polarity as a third degree of freedom. Instead of only varying charge magnitude (0 or 1), the system now varies charge polarity (positive, negative, or zero). This dimensional addition to the storage parameter space enables more efficient representation of computational data and operations.

AI summary
A system and method for bidirectionally based electrical information storage, processing and communication. Bidirectional memory (tristate) offers the capability to store and interpret multiple bits (Shannon's) of information per memory cell, for structures such as dynamic random-access memory (DRAM), and read-only memory (ROM), and communication circuits, for operation, rather than traditional memory able to store a single “bit” (Shannon) of information per cell. Where, instead of traditional memory cells capable of two possible states (binary digit) and a single defined bit (1 Shannon), bidirectional memory is capable of three states (tristate), where the third information representing state can be a specifically defined state capable of representing multiple bits (multiple Shannon's) for each individual cell, which may be defined to represent a specific sequence of bits (sequence of Shannon's). Additionally, the 3rd information state of a tristate bidirectional memory cell may be expressed as in a state of constant variability (superposition), where the final determined state may be based on a probabilistic outcome, or probability controlled. The disclosed system and method allows for more complex systems for information storage, compression, processing, communication, and more secure encryption of stored or communicated information.
