ABSTRACT:
An integrated circuit with a secure memory location is comprised of a memory and a circuit which receives a twenty-four bit command word. At least one location in the memory stores at least one secure subkey. The circuit responds to the command word with an access to a secure memory location if and only if the command word specifies a starting address of a secure subkey and the command word is transmitted in both true and bit complimented form. Each subkey is made up of a 64-bit ID field, a 64-bit password field and a 384 bit secured data field.
