Abstract

Disclosed is a technique whereby high density memory cubes are mounted in multiple-cube arrays onto high density hermetically sealed cards to achieve massive amounts of data storage capacity in minimal space. A typical expected application would be the development of solid-state recorders for use in space satellites. Currently these space recorders are predominantly mechanical tape-type devices and are much less reliable and more cumbersome than solid-state alternatives would be. The reliability concern is so pronounced that entire spare recorders are sometimes installed to ensure adequate performance. Solid-state recorders would also offer increased programming versatility.

Ultra-High Density Data Storage Through Memory Cubes on Hermetic Cards

      Disclosed is a technique whereby high density memory cubes are
mounted in multiple-cube arrays onto high density hermetically sealed
cards to achieve massive amounts of data storage capacity in minimal
space.  A typical expected application would be the development of
solid-state recorders for use in space satellites.  Currently these
space recorders are predominantly mechanical tape-type devices and
are much less reliable and more cumbersome than solid-state
alternatives would be.  The reliability concern is so pronounced that
entire spare recorders are sometimes installed to ensure adequate
performance.  Solid-state recorders would also offer increased
programming versatility.  To date though, their emergence has been
stifled by the lack of a radiation-hardened, space-qualified
solid-state means of handling the enormous data storage requirements
in the minimal amount of physical space available.  This disclosure
addresses this need.

      The Figure depicts the memory cube in hermetic card solution.
By populating a double-sided High Density Hermetic Card (HDHC) 1 with
a large number of memory cubes 2 orders of magnitude of improvement
over the prior-art space memory packages can be obtained.  The Figure
depicts a HDHC populated with 32 cubes per side at 640 Mb per cube
(i.e., 40 16Mb chips per cube) through the use of silicon substrated
8-cube/1-chip sub-components 3 for a total c...
