Abstract
A memory system for limiting access of a protected portion of a memory to a predetermined accessing device. The memory system includes a memory having a protected portion. The system further includes a control unit in communicative relation with an accessing device and the memory, wherein the control unit monitors the accessing device's pattern of access to the memory in order to determine if the accessing device is the predetermined accessing device and permits only the predetermined accessing device to access the protected portion of the memory.
Claims20
A memory system for limiting access of a protected portion of a memory to a predetermined accessing device, comprising:
- (a) a memory having a protected portion;
- and
- (b) a control unit in communicative relation with an accessing device and the memory, wherein the control unit monitors a pattern of access to the memory of the accessing device in order to determine if the accessing device is the predetermined accessing device and permits only the predetermined accessing device to access the protected portion of the memory.
An enhanced module chipping system for use in conjunction with an engine control unit of an automobile comprising:
- (a) a memory having loaded thereon at least one performance profile for the engine control unit to run;
- (b) a control unit in communicative relation with the memory;
- and
- (c) an interface port in communicative relation with the control unit and the memory, wherein the interface port is configured for connection to a programming device for modifying the at least one performance profile.
A method of modifying performance characteristics of an automobile that includes a subsystem for performing a predetermined function, the method comprising:
- (a) modifying data stored in a memory of an engine control system;
- and
- (b) reprogramming the subsystem of the automobile such that the subsystem is capable of both performing the predetermined function and controlling access of the engine control unit to the modified data.
