Abstract:
Memory space management and memory access control method and apparatus are provided. The method includes: upon receiving an access request, acquiring an access address and an accessor identifier in the access request; checking a current state of a memory space pointed by the access address to obtain a check result, wherein the state of the memory space includes a first state and a second state; determining whether the accessor identifier belongs to an access permission set among a plurality of access permission sets that corresponds to the check result; and generating an instruction according to the check result, wherein the instruction indicates whether or not the accessor is permitted to access the memory space. With the above method, the invention reduces resource waste and system costs.

Claim (Index 16):
The memory access control apparatus according to  claim 15 , being characterized in that, when the first control bit is a first word, it means that the memory space is in the first state; when the first control bit is a second word, it means that the memory space is in the second state; if the check result indicates that the first control bit is the first word, the determining unit generates the determination signal according to the search result of a first protection group among the plurality of protection groups; and if the check result indicates that the first control bit is a second word, the determining unit generates the determination signal according to the search result of a second protection group among the plurality of protection groups.
