DDR2 SDRAM Memory

The Pico E-15 comes equipped with 256MB of DDR2 SDRAM memory. There are two 1024Mb chips, each with a separate 16 bit data path to the host to form one 32 bit bank. From 0°C to +85°C, the ram can run at up to 333 MHz. For operation at temperatures below 0°C, special firmware with throttled ram timings is required. Please note that the RAM will not function below 125 MHz.
