Abstract
A secondary memory unit includes a first substrate that has a non-volatile memory unit mounted thereon that is configured to receive power from an external power supply. A second substrate has an energy storage and supply medium mounted thereon. An energy transfer medium is provided that electrically connects the first substrate and the second substrate. The energy storage and supply medium is configured to supply an operating power to the non-volatile memory unit when power from the external power supply to the non-volatile memory unit is cut off.
Claims20
A secondary memory unit comprising:
- a first substrate;
- a non-volatile memory unit that is mounted on the first substrate and which is configured to receive power from an external power supply;
- a second substrate that is separate from the first substrate;
- an energy storage and supply medium that is mounted on the second substrate;
- and
- an energy transfer medium that is configured to electrically connect the first substrate and the second substrate,
- wherein the energy storage and supply medium is configured to supply an operating power to the non-volatile memory unit when power from the external power supply to the non-volatile memory unit is cut off.
A secondary memory unit comprising:
- a first substrate on which one or more non-volatile memory units are mounted;
- and
- a first case in which the first substrate is accommodated,
- wherein the first case comprises a first terminal configured to supply normal power to the non-volatile memory units from a primary power source that is external to the first case and a second terminal configured to supply a backup operating power to the non-volatile memory units from a backup power source that is external to the first case when the normal power is cut off.
A secondary memory unit, comprising:
- a first case that includes a first substrate that has a non-volatile memory unit mounted thereon;
- a second case that has a second substrate that has an energy storage and supply medium mounted thereon;
- and
- an energy transfer medium that electrically connects the first substrate to the second substrate and that is configured to selectively supply energy from the energy storage and supply medium to the non-volatile memory unit in response to power to the first substrate from a power supply that is external to the secondary memory unit being cut off.
