SERIAL FLASH DISCOVERABLE PARAMETERS (SFDP)	JESD216F.01	Feb 2022
The Serial Flash Discoverable Parameter (SFDP) standard provides a consistent method of describing the functional and feature capabilities of serial flash devices in a standard set of internal parameter tables. These parameter tables can be interrogated by host system software to enable adjustments needed to accommodate divergent features from multiple vendors. Any company may request a Function Specific ID by making a request to the JEDEC office at juliec@jedec.org. Please include “Function Specific ID Request, JESD216” in the email subject line.

High Bandwidth Memory DRAM (HBM3)	JESD238	Jan 2022
The HBM3 DRAM is tightly coupled to the host compute die with a distributed interface. The interface is divided into independent channels. Each channel is completely independent of one another. Channels are not necessarily synchronous to each other. The HBM3 DRAM uses a wide-interface architecture to achieve high-speed, low power operation. Each channel interface maintains a 64 bit data bus operating at double data rate (DDR). Item 1837.98. Committee(s): JC-42.2 Free download. Registration or login required.
