SD Express Card: Background
Client Computing, Imaging, Automotive – Transition to Higher Speed Interfaces

New Markets Demand More Memory with Higher Speed

 Autonomous vehicles and connected cars with multi-sensor data collection & processing Multi-channel video capture Gaming with 3D high resolution graphics
 New evolving imaging market(360o, VR, AR etc…)

Advantages of PCIe Interface

PCIe® standard developed by PCI-SIG• PCIe Gen 3 (up to 8Gb/s) and Gen 4 (up to 16Gb/s) are proven….
• PCIe released already Gen 5 and Gen6 is underway…



NVMe™ standard developed by NVM Express
The command layer protocol for Non Volatile Memories that teamed up with PCIe…
A scalable and sophisticated protocol – ready to handle future system needs
Become more and more popular as the de-facto standard for SSDs and others…
Supported by all major OS’s
Proven test environments were defined®

Both are recognized worldwide as the preferable protocols for future needs  Easy to adopt!

PCIe and NVMe Interfaces – Test Advantages
Many Bus Analyzers, Protocol Analyzers, Test Suites are in the market…

Summary of New SD Standards
SDA defined performance standards for sequential writes serving the imaging market with focus on growing demands of video capturing
SDA defined UHS-III (624MB/s) to further enhance these market needs
But its not just storing content …its App Running demanding enhanced random access…
SDA defined Application Perf Class A1(Nov.2016) and A2 (Feb.2017) along with enhanced features; Command Queuing, Cache and Maintenance

Evolving technology trends of mobile SoCs raised a request to operate only with 1.8v Signaling (w/o need for 3.3v initialization)
SDA defined the Low Voltage Signaling card with full backward compatibility

New evolving technologies of multi-core, high-speed IOs with SD Express PCIe Gen.3 ＆ Gen.4 NVMe will raise even higher demands for
SD card performance in high end applications

1.8W Max. Power Consumption vs (Normal SSD ~ 3W)
Bus Mastering for inter chip communication between devices tohelp efficient latency path and longer battery life
Dedicated CMD Queue in DRAM for every CPU core
Host Memory Buffer (HMB) to save cost (No SRAM Model)
Backward Compatibility with SD Interface©SD Association. All Rights Reserved.

SVP Overview☐ SVP -SD Express/UHS-II Verification Program☐ SDA runs the program allowing SDA members to check UHS-II electricalconformance and SD Express Electrical /PCI Express protocol conformance.
The product which passes the test will be listed as Verified Product. The list
will be open to public.
☐ SVP provides better interoperability and cost effective option for partial
conformance test for SDA members.
☐ Two options in Test Schedule
1)Test Shuttle : Fixed Test Schedule and Share test cost with multiple
members (1st Round (closed) : Sep 13, 2nd Round : Planned in Jan 2022)
2)On Demand : Test immediately©SD Association. All Rights Reserved.

54

How SVP helps SDA members and End Users☐ Data Rate gets higher and protocol gets complicated. At the same time, therisk of interoperability gets higher. However large investment is involved tocreate test environment. SVP provide cost effective option to assess the riskof signal integrity and protocol conformance.
☐ SDA is subsidizing SVP in initial phase to enable the program quickly.
☐ SDA will publish the list of products which pass SVP. User will see theproducts qualified in a certain quality requirement.

Backwards Compatibility – to UHS-I/II

How Important is Backwards Compatibility?
• It is critical to the launch success of SD Express• The opposing standard is not backwards compatible, thus giving SD Express a HUGE selling advantage• Must include Hosts, OS and Readers
SDA has carved out a unique position in allowing this.

Summary

Consumers can “Future Proof” themselves by buying aform factor that works in their current hosts, but is also
fast enough for high-resolution video capture and highspeed data transfers that are likely to be available infuture hosts.
Even today, the advantage of the improved workflow
speeds makes it a viable product.
