  • Memory modules with voltage regulation and level translation
    Patent number: 5757712
    Abstract: Low voltage DRAMs are used on higher voltage memory modules in a way that requires no modification of the DRAMs. "Bus switch" technology and compact low voltage regulators are used at the module level. The low voltage regulator provides a lowered, regulated voltage to DRAMs. The bus switches are used at the inputs and outputs of the DRAMs and effectively protect the DRAM circuitry from voltage swings that could otherwise be damaging.
