Solid State Non-Volatile Storage Drives Having Self-Erase and Self-Destruct Functionality and Related Methods
First Claim
1. An internal solid state storage drive for a host computer, comprising:
- a solid state memory cell array that includes a plurality of non-volatile memory cells;
a first processor that is configured to control write operations to the solid state memory cell array and read operations from the solid state memory cell array; and
a second processor that is separate from the first processor, the second processor configured to block erase substantially all data blocks of the solid state memory cell array in response to a user input self-erase command.

Abstract
Solid state storage drives for a host computer are provided that include a solid state memory cell array that includes a plurality of non-volatile memory cells, a first processor that is configured to control write and read operations to and from the solid state memory cell array, and to perform block erase operations on blocks of the solid state memory cell array, and a second processor that is configured to block erase all blocks of the solid state memory cell array in response to a user input self-erase command. These solid state storage drives may further include self-destruct functionality which can be used to render the drive unusable and to inhibit efforts to forensically recover data that was previously stored on the drive.

12. An internal solid state storage drive, comprising:
-
a housing; a solid state memory cell array within the housing; a battery within the housing; a power supply circuit that receives power from the battery; a self-destruct circuit that is powered by the power supply circuit, the self-destruct circuit configured to deliver a high voltage to the solid state memory cell array that renders the memory cells of the solid state memory cell array inoperable in response to a user input self-destruct command. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method of preventing access to data stored within a solid state memory cell array of an internal solid state storage drive for a computer, the method comprising:
-
receiving a self-erase command via a user input circuit; block erasing erase substantially all data storage blocks of the solid state memory cell array in response to the received self-erase command; and
thendelivering a high voltage to the solid state memory cell array that renders the memory cells of the solid state memory cell array inoperable. - View Dependent Claims (20)
