Modern switching circuits prefer "soft recovery" diodes, which reduce voltage spikes and ringing. JESD794D defines two portions of the recovery waveform:
The only authoritative source is the (jedec.org). As of this writing, JESD794D is an active standard. jesd794d pdf
The full 270-page document is a comprehensive guide for engineers and manufacturers. Key sections typically include: JEDEC - JESD79-4D - DDR4 SDRAM - Standards | GlobalSpec jesd794d pdf
The document is dense. Navigating the PDF can be cumbersome due to the sheer volume of parameter tables. However, the inclusion of detailed state diagrams in the early chapters is highly valuable for logic designers modeling the memory controller. jesd794d pdf
