Abstract
For solid state drive (SSD) or other memory system formed of multiple memory dies, techniques are presented for operation in a standby mode with increased power savings. The memory dies are operable in a regular standby mode and in a low power standby mode. Based upon the amount of current each of the memory dies in the regular standby mode, when the device goes into standby the memory dies that draw higher amounts of current when in the regular standby mode are instead placed into the low power standby mode. The amount of current drawn by each of the memory die in the regular standby mode can be determined for each of the memory dies at die sort or as part of the memory test process, or can be determine by an assembled SSD itself.
