occasionally been used as a replacement for embedded memory since they offer easier maintenance and serviceability in the field. Typically, these cards serve as memory expansion to complement a relatively small embedded memory.<br /> The Part 1 of the Physical Layer Specification V9.0 (SD9.0) introduces new optional features for SD memory cards enabling it to better serve as semi-embedded memory or applications in which the card needs to be tightly bound to specific host:</p> <p>Boot – Fast Boot and Secure Boot features give cards the ability to serve as a device’s boot code memory by using a simple and easy fast boot code uploading process, along with secured methods of providing boot code updates</p> <p>RPMB – Replay Protected Memory Block offers a secured hidden memory accessible only through a secured authentication process and provides replay protection security mechanism: especially for a secured write-protect mechanism and secured boot code update</p> <p>TCG Storage – A secured storage method defined by the Trusted Computing Group adding a self-encrypted drive capability</p> <h3>White Paper:</h3> <ul> <li><a href="https://www.sdcard.org/cms/wp-content/uploads/2022/05/Boot-TCG-and-RPMB-The-New-Security-Featu-res-Introduced-in-SD-9.0.pdf">SDA_TCG, RPMB and Boot – The New Security Features introduced in SD 9.0</a></li> </ul> </section> <footer class="article-footer"> </footer> </article> </main> </div> </div> <footer class="footer" role="contentinfo" itemscope itemtype="http://schema.org/WPFooter"> <div id="inner-footer" class="wrap cf"> <nav role="navigation"> </nav> <div class="copy"> <p class="mt15 mb5"><span>SD and related marks and logos are trademarks of SD-3C LLC.</span></p> <p class="mb5">© 2000 - 2024 SD-3C LLC.
