Ultra-Low-Power DRAM: A “Green” Memory in IoT Devices

Winbond is offering a new way to extend the power savings available from Partial Array Self-Refresh (PASR), which was already specified in the JEDEC standard by implementing a new Deep Self-Refresh (DSR) mode. DSR operates in a similar way to PASR at low data rates, allocating used data to one or more banks, in which data are refreshed, and allowing the remaining banks to lose their data by stopping the refresh current from flowing to them.
