What makes Panasonic SD memory cards so uniquely reliable?
SD Cards – the most preferred flash storage technology
User-friendly design, compact size and superior performance make SD memory cards ideal for usage in all types of electronic products, including digital cameras, camcorders, music players, smart phones, home theater components, and emerging wearable and IoT devices.
Rising media consumption, an explosion in personal data storage, and the IoT are spurring demand. As content and data expand, so do storage needs. Meanwhile, electronic manufacturers are demanding affordable and reliable storage media for their products.
Discover higher reliability with Panasonic storage media
To answer the demand of the market, Panasonic offers uniquely designed, robust SD cards that offer higher reliability using the latest technology in flash memory, a proprietary controller with on-chip error correction, and ingenious firmware algorithms. Three Panasonic SD Card product lines – consumer, consumer plus, and industrial – offer more than 50 products to handle all your SD card needs, including security, video, medical, and automotive applications.
Panasonic’s Industrial SD Cards feature twice the physical strength of standard SD card offerings and are built for ruggedized solutions. Operating temperature of -40°C to +85°C is standard along with an extended 60k write cycle for the highest endurance in an SLC card. The SD/SDHC memory cards implement built-in industrial NAND flash memory in both Single Level Cell (SLC) and Multi Level Cell (MLC) cards.
Built to meet the most demanding requirements of industrial and commercial applications, Panasonic Industrial SD Cards operate in severe environmental conditions, prevent data corruption due to power failure, and deliver high program/erase endurance.
Consumer Plus SD Cards are MLC/pSLC NAND flash memory cards designed for high endurance and high capacity applications. Operating temperatures are -40°C to +85°C or -25°C to +85°C.
Consumer SD Cards include TLC NAND flash memory cards that offer long lifetime usage and high system performance. The standard operating temperature range is -25°C to +85°C.
What makes Panasonic SD cards so uniquely reliable?
Proprietary Panasonic controller with ingenious firmware algorithms
Controller firmware manages an SD card’s interface, buffer, on-chip ECC engine, NAND interface, and NAND block management. The performance and reliability of SD memory cards utterly depends upon the quality and ingenuity of the firmware algorithm design.
For Panasonic SD Cards, an exclusive Panasonic-designed SD controller with ingenious algorithms and programmed intelligence provides bad block management, effective wear leveling, error correction and data recovery – thereby improving SD card performance, reliability and longevity. Panasonic’s unique controller provides greater control over customization options and the SD card’s firmware.
Data writing and rewriting endurance maximizes card life
Static wear levelling controls written data, including fixed data. Various use cases eliminate intensive data writing and maximize the lifetime of the SD card.
Dispersion of writing stress to NAND memory reduces disturbances
Intelligent data writing disperses the writing stress to NAND flash memory, reducing program disturbances.
Power failure robustness and recovery protects data and the device
Unique Panasonic algorithms minimize data damage in the event of a power failure. Even if an error is generated, the controller recovers the data and restores it to the condition prior to the error – this is especially valuable for applications with unstable power conditions.
On-chip ECC with bit error auto refresh assures no read errors
Panasonic SD cards deliver secure storage with bit error auto refresh that withstands repeated recording operations. Bit error auto refresh automatically refreshes the bit errors that accumulate over time, before they exceed the threshold. Panasonic’s on-chip ECC engine adds a small amount of data – called the error correction code – to written data prior to programming to the NAND flash memory. If a bit error occurs in the NAND flash memory, the ECC-engine will correct the read data, allowing the SD card to output corrected data.
The number of bit errors that can be corrected depends on the method of the ECC engine. Generally, the greater the ECC area within the NAND flash, the higher the error correction capability. ECC is stored in a spare area of flash memory that includes other system information. Limited space for ECC means limited error correction capability. Panasonic’s SD card controller uses the spare area of flash memory with extreme efficiency and assigns sufficient space for ECC. As a result, Panasonic’s ECC engine has above-average error correction capabilities.
The enhanced error correction capabilities improve data retention and endurance, protecting the SD card from bit error over time. For example, Panasonic industrial grade SD card with SLC NAND flash memory can tolerate 100k endurance cycles for a one-year data retention time.
Rigorous quality standards and extensive testing
Panasonic performs extensive and rigorous in-house quality testing for all SD cards. Panasonic is also committed to using a fixed and controlled Bill of Materials (BOM) to assure the highest quality and reliability for every chip that leaves the fab. By offering a fixed BOM, Panasonic pledges that any change to core SD card components – the NAND flash memory, the SD controller IC, and the firmware – requires a product change notification. In addition, many Panasonic SD cards are AEC-Q100 certified, solidifying their rank amongst top competitors.
