DDR3 reset function
The reset is an important new function of DDR3, and a pin has been specially prepared for this purpose.
The DRAM industry has long requested that this feature be added. Now it is finally implemented on DDR3. This pin will make DDR3 initialization easier.
When the Reset command is valid, DDR3 memory will stop all operations and switch to the least active state to save power.
During Reset, DDR3 memory will close most of the internal functions, all data receivers and transmitters will be shut down, all internal program devices will be reset, DLL (delay phase-locked loop) and clock circuits will stop working, and ignore Any movement on the data bus.
This will enable DDR3 to achieve the most power-saving goals.
