Abstract
What is disclosed is a memory module to and from which multibit binary words are stored and read out. Each multibit binary word comprises a standard byte size and one or more other memory bits that may be used for purposes such as parity checking. The modules may be mounted on a printed circuit mother board from which power, control signals and binary words are applied to and taken from the module.
Claims2
A memory module for installation on a printed circuit motherboard comprising
- nine data memory chips for storing digital data, each having a data input and output, control input, and an address input, and each being packaged in a plastic leaded chip carrier, wherein said ninth memory chip is for storing detection and correction information associated with the eight data memory chips,
- an expoxy-glass printed circuit board substrate having a length and width adequate for mounting thereon only in a single row said nine memory chips and for interconnecting the control inputs and the address inputs of the memory chips so that bytes of digital information may be input to or output from the memory chips,
- the substrate including thirty terminals for providing access to the data inputs and outputs, control inputs, and address inputs of the nine memory chips and to enable reading and writing of information into and out of the nine chips,
- support means for supporting the memory module at an angle with respect to a motherboard and
- decoupling capacitors mounted on said substrate and coupled to the memory chips for suppressing transient voltages.
