144 pin SO-DIMM SDRAM Modules
Serial Presence Detects
A serial presence detect storage device - E²PROM - is assembled onto the module. Information
about the module configuration, speed, etc. is written into the E²PROM device during module
production using a serial presence detect protocol ( I²C synchronous 2-wire bus)
