CompactFlash (CF)

Memory chips and cards are key electronic device components manufactured according to memory size, physical size, volatile/non-volatile features, compatibility and other specifications. CF technology is also strong in the camera memory market.

CF types are as follows:

• Type-I: Almost 3.3 mm thick
• Type-II: 5.0 mm thick. Used for different microdrive types. Four speed categories.

CF's technical features are as follows:

• Speed: Speed calculation method is similar to CD-ROM. Normally, standard speed is up to 150 kbps. However, each card has an embedded speed limit.
• Solid structure: Available with solid states. Provides extra user data protection, versus magnetic storage discs. Does not contain any moveable parts.
• Error Correction/Read/Write: General read process to power CF occurs at startup. Errors are checked and recovered.
• Reliability: Compared to rotating media devices, CF is more flexible and reliable because there are no moving parts, which ensures error correction and data integrity. CF is also non-volatile, which reduces the electricity dependency of motherboard memory cards and chips.
• Comparatively best option: Durable in many scenarios, compared to other memory cards. CF cards are compatible with ATA/IDE and may be used in any board supported by Integrated Development Environment - .NET (IDE).
• Cryptographic features: No built-in cryptographic or Digital Rights Management (DRM) features.

CF cards are also available with higher storage capacity, versus other memory cards. Potential damage occurs if a CF card is improperly inserted into a device. However, to prevent such mistakes, slots are designed for proper insertion.
