State Store: Storage Capacity 8GB to 256GB

Component Specifications

Definition

The State Store is a specialized memory component within Transaction State Manager machines that provides non-volatile storage for transaction states, ensuring data persistence across power cycles and system interruptions. It captures and retains the complete state of industrial transactions including process parameters, operational status, error logs, and recovery points, enabling reliable rollback and continuity in automated manufacturing environments.

Working Principle

Operates on persistent storage technology (typically NAND flash or MRAM) with wear-leveling algorithms and error correction codes. It receives state data from transaction processors, writes it to non-volatile memory cells, and provides read access for state recovery. Includes power-loss protection circuits to ensure data integrity during unexpected shutdowns.

Materials

Silicon wafer with NAND flash memory cells or Magnetic Tunnel Junction (MTJ) cells for MRAM variants; PCB substrate (FR-4); Gold-plated contacts; Epoxy encapsulation; Thermal interface material for heat dissipation.
