Technical details and manufacturing context for State Memory Module

Definition

The State Memory Module is an electronic component integrated into the State Monitor system, responsible for storing historical and current operational state data from monitored equipment or processes. It serves as the data retention unit that preserves state information for analysis, diagnostics, and system recovery purposes. The module receives digital state data from sensors and monitoring circuits, processes this information through its memory controller, and stores it in non-volatile memory cells. It maintains data integrity through error correction algorithms and provides read/write access to the main State Monitor processor for data retrieval and updates. Key specifications include a storage capacity of 1–8 GB, data retention time of 10–20 years at 25°C when powered off, write endurance of 100,000–1,000,000 cycles depending on NAND type, and an operating temperature range of -40 to 85°C. The module operates at a supply voltage of 3.3 V DC ±5%, with power consumption between 0.5 and 2 W in active mode. It supports I2C and SPI interfaces, with data transfer rates of 10–100 Mbit/s in SPI mode. The module is designed for industrial environments, with non-condensing humidity tolerance of 5–95% RH, and ingress protection ratings from IP40 to IP65 depending on the enclosure. Physical characteristics include a weight of 50–200 g without enclosure and dimensions ranging from 50×30×10 mm to 100×60×20 mm for the board only. Materials used include semiconductor silicon, copper traces, and epoxy resin substrate. These values are reference ranges; verify model-specific specifications with the manufacturer or supplier before procurement.

Working Principle

The module receives digital state data from sensors and monitoring circuits. The memory controller processes this data and writes it to non-volatile memory cells. Error correction algorithms maintain data integrity. The main State Monitor processor can read or update the stored data via the interface. The module ensures data retention even when power is off, supporting diagnostics and recovery.
