1Use of energy by moving object

If data masking operation is performed during write operation, then power consumption is reduced, but device complexity increases

Engineering Contradiction:
Improvepower consumptionVSAvoiddevice complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The write operation is segmented into multiple phases: normal write operation phase and data masking operation phase. The controller selectively activates either the normal write path or the data masking path based on the masking signal, dividing the operation into distinct functional segments that can be independently controlled to optimize power consumption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller performs preliminary detection of the masking signal before executing the write operation. Based on this preliminary detection, the controller pre-configures the data path by activating either the normal write path or the data masking path, ensuring that power-consuming components are only activated when necessary for the specific operation type.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If data masking operation is performed, then data storage efficiency is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvedata storage efficiencyVSAvoidmanufacturing precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The data path is segmented into separate routing channels: a normal write path for standard operations and a data masking path for selective writing. This segmentation allows the system to achieve high data storage efficiency by selecting the appropriate path, while the standardized design of each path maintains manageable manufacturing precision requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The write operation circuit is designed with multi-functionality to handle both normal write operations and data masking operations using the same physical infrastructure. The controller universally manages both operation types by selectively activating different paths, improving data storage efficiency without requiring entirely separate manufacturing processes for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An electronic device includes an operation control circuit and an input data generation circuit. The operation control circuit generates a detection signal and an internal masking signal based on a masking signal and data during a write operation. The input data generation circuit converts input data based on the internal masking signal to generate converted data. In addition, the input data generation circuit selects and outputs either the converted data or drive data as the input data, which are input to a data storage circuit, based on the detection signal.
