One of the many new features included in the PCI Express^® (PCIe^®) specification will be PAM4 (Pulse Amplitude Modulation with 4 levels) signaling.

The SD Association (SDA) recently announced SD Express, which adds the PCI Express^® and NVMe™ interfaces to the SD interface. The PCIe^® interface delivers transfer rates up to 985 megabytes per second (MB/s) and supports backward compatibility with existing SD hosts.

I’m looking forward to attending the Flash Memory Summit (FMS) next week in Santa Clara.
