Double Data Rate Synchronous Dynamic Random-Access Memory, officially abbreviated as DDR SDRAM, is a double data rate (DDR) synchronous dynamic random-access memory (SDRAM) class of memory integrated circuits used in computers. DDR SDRAM, also retroactively called DDR1 SDRAM, has been superseded by DDR2 SDRAM, DDR3 SDRAM and DDR4 SDRAM. None of its successors are forward or backward compatible with DDR1 SDRAM, meaning DDR2, DDR3, and DDR4 memory modules will not work in DDR1-equipped motherboards, and vice versa.
Dimm memory module having electronic fuse
The present invention relates to a memory module having an electronic fuse which protects devices within the memory module by shutting off excessive current or voltage in an electrical overstress condition in which the excessive current or voltage is applied, the memory module comprising: a memory device array composed of a DDR SDRAM; a register clock driver chip which distributes signals received from a memory controller to the memory device array; a power management integrated circuit chip which distributes and supplies input power to components including the memory device array and an RCD; a serial configuration recognition chip which stores initial device information; and an electronic fuse which shuts off the input power when the input power is under electrical overstress, wherein the memory module may further comprise an electronic fuse integrated package in which the register clock driver chip or the power management integrated circuit chip and the electronic fuse are embedded in a single package.
