The TS (temperature sensor) chip is an important chip in DDR5, As a slave device of the SPD Hub, the TS can operate on I2C buses with clock frequencies up to 1MHz and I3C buses up to 12.5MHz. The server CPU can communicate with the TS via the SPD Hub to achieve temperature management of the memory modules.
