Hi thanks for the initial information, we are currently using a modem which contains this device and would like to know about data retention period of this device, i understand the psram is a combination of Dram and sram but these two have the following DRAM cells store data in the form of charge on a capacitor. This charge leaks off over time, eventually causing data to be lost. ... These problems are expected to worsen as DRAM density increases. The amount of time that a DRAM cell can safely retain data without being refreshed is called the cell's retention time. So what would be the data retention of this device in terms of degradation with power and without power but after initial programming ?
