GE-645
<computer> A computer built by {General Electric}, the
successor to the {GE-635}, designed to provide the extra CPU
features required by the {Multics} project.
The GE-645 was designed in 1965 by John Couleur and Edward
Glaser at MIT. It had several security levels and
instructions for handling {virtual memory}. Addressing used
an 18-bit segment in addition to the 18-bit address,
dramatically increasing the theoretical memory size and making
virtual memory easier to support.
Design of the GE-645's successor, the {GE-655}, started in 1967.
