Component Specifications

Definition
Flash memory is a type of non-volatile computer storage that can be electrically erased and reprogrammed. In Bluetooth modules, it stores firmware, configuration data, pairing information, and user data persistently without requiring power. It uses floating-gate transistors organized in memory cells (typically NAND or NOR architecture) to retain data through charge trapping in an insulated floating gate.
Working Principle
Flash memory operates by storing electrical charges in floating-gate transistors. Writing (programming) involves applying voltage to control gates to inject electrons into the floating gate through quantum tunneling, changing the transistor's threshold voltage. Erasing removes electrons via Fowler-Nordheim tunneling. Reading detects the threshold voltage state to determine stored data (0 or 1). NAND flash (common in modules) uses serial access for high density, while NOR allows random access.

Silicon wafer substrate, polysilicon floating gate, oxide insulation layers (SiO2), metal interconnects (copper/aluminum), plastic/epoxy packaging.

Frequently Asked Questions

Why is flash memory used in Bluetooth modules?

Flash memory provides persistent storage for firmware, device settings, and pairing data without power consumption, enabling Bluetooth modules to retain critical information through power cycles.

What is the difference between NAND and NOR flash in this application?

NAND flash offers higher density and lower cost per bit, making it suitable for storing larger firmware files in Bluetooth modules. NOR flash allows execute-in-place capability but is less common due to higher cost.

How does flash memory affect Bluetooth module performance?

Access speed and interface (SPI vs parallel) impact firmware loading time and data transfer rates. Higher endurance ratings ensure reliability over the product lifecycle.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
