Data Coding Device Bit Counting Inversion for Storage Efficiency

The patent replaces mechanical hard disk systems with nonvolatile memory devices that use electrical or magnetic field-based storage mechanisms. The memory controller uses digital signal processing and data encoding/decoding circuits to manage storage operations, eliminating the need for mechanical components and achieving miniaturization while maintaining storage capacity.

The memory controller performs preliminary data encoding and preprocessing operations before data is written to the nonvolatile memory. By preparing data in advance and organizing it optimally, the system achieves high performance despite the smaller memory size, as the preprocessing compensates for the limited capacity and speed of miniaturized memory components.

The nonvolatile memory device maintains its stored data without requiring continuous power supply, inherently providing power efficiency. The memory controller is designed to enter low-power states when not actively transferring data, and uses efficient data encoding schemes that reduce the number of write operations needed, thereby minimizing energy consumption in miniaturized portable devices.

The memory controller counts reference data bits and performs data inversion only when the count reaches a predetermined threshold, rather than continuously inverting all data. This partial action approach maintains data conversion accuracy by inverting only when necessary, while significantly reducing processing time by avoiding unnecessary inversion operations.
