Abstract
The embodiments of the invention describe settings, commands, command signals, flags, attributes, parameters or the like for signed access prior to allowing data to be written to (e.g., a write access), read from (e.g., a read access) or erased from (e.g., an erase access) protected areas of a memory device (e.g., a region, logical unit, or a portion of memory in the storage module).
Claims20
A memory device comprising:
- a plurality of addressable memory locations, each addressable memory location of the plurality of addressable memory locations having at least one memory cell, the plurality of addressable memory locations collectively forming a storage;
- and
- one or more controllers operable to:
- receive a request for a read access to a logical portion of the storage;
- read, as read data, data associated with the logical portion of the storage;
- determine, based at least in part on a configurable setting and as a determination, that signed access to the logical portion is enabled;
- sign, as signed data, the read data associated with the logical portion of the storage based at least in part on the determination that signed access to the logical portion is enabled;
- and cause the signed data to be sent at least partially in response to receiving the request for the read access.
5 more elements
A method comprising:
- receiving, at a memory device, a request for a read access to a logical portion of a storage associated with the memory device;
- reading, as read data and by a controller of the memory device, data associated with the logical portion of the storage;
- determining, based at least in part on a configurable setting, that signed access to the logical portion is enabled;
- signing, as signed data and by the controller of the memory device, the read data associated with the logical portion of the storage based at least in part on the determining that signed access to the logical portion is enabled;
- and
- sending, by the memory device, the signed data at least partially in response to receiving the request for the read access.
3 more elements
A host device comprising a controller operable to:
- send a request for a read access of a logical portion of a storage associated with a memory device;
- receive a reply from the memory device at least partially in response to sending the request, the reply indicating that the memory device is required, based at least in part on a configurable setting indicating that signed access to the logical portion is enabled, to sign the data based at least in part on a parameter to be received from the host device;
- send the parameter to the memory device at least partially in response to receiving the reply;
- receive signed data associated with the logical portion of the storage at least partially in response to sending the request for the read access;
- and
- use the signed data for signed booting of the host device.
