A memory device comprising: a memory comprising: at least one physical partition (902; 904; 906) comprising: a first region of the memory storing metadata including one or more elements (602; 604; 606) to store one or more element values indicative of at least one characteristic related to a portion of the at least one physical partition of the memory, the one or more element values comprises an element with a current element value already stored in the element; and a second region of the memory storing data at least partly in the portion of the memory; and a controller, characterized in that the controller is configured to: receive a request, from a host device, to read the current element value from the element; identify a reference value stored in a register setting of the memory device, the reference value indicating a capacity of the at least one physical partition of the memory; subtract at least a size of the first region of the memory from the capacity of the at least one physical partition to derive a derived reference value; determine that the current element value already stored in the element exceeds the derived reference value; prevent reading out of the current element value to the host device; and provide the derived reference value instead of the current element value to the host device in response to receiving the request to read the current element value to ensure that the request to read the current element value is valid. a memory comprising: at least one physical partition (902; 904; 906) comprising: a first region of the memory storing metadata including one or more elements (602; 604; 606) to store one or more element values indicative of at least one characteristic related to a portion of the at least one physical partition of the memory, the one or more element values comprises an element with a current element value already stored in the element; and a second region of the memory storing data at least partly in the portion of the memory; and a first region of the memory storing metadata including one or more elements (602; 604; 606) to store one or more element values indicative of at least one characteristic related to a portion of the at least one physical partition of the memory, the one or more element values comprises an element with a current element value already stored in the element; and a second region of the memory storing data at least partly in the portion of the memory; and a controller, characterized in that the controller is configured to: receive a request, from a host device, to read the current element value from the element; identify a reference value stored in a register setting of the memory device, the reference value indicating a capacity of the at least one physical partition of the memory; subtract at least a size of the first region of the memory from the capacity of the at least one physical partition to derive a derived reference value; determine that the current element value already stored in the element exceeds the derived reference value; prevent reading out of the current element value to the host device; and provide the derived reference value instead of the current element value to the host device in response to receiving the request to read the current element value to ensure that the request to read the current element value is valid. receive a request, from a host device, to read the current element value from the element; identify a reference value stored in a register setting of the memory device, the reference value indicating a capacity of the at least one physical partition of the memory; subtract at least a size of the first region of the memory from the capacity of the at least one physical partition to derive a derived reference value; determine that the current element value already stored in the element exceeds the derived reference value; prevent reading out of the current element value to the host device; and provide the derived reference value instead of the current element value to the host device in response to receiving the request to read the current element value to ensure that the request to read the current element value is valid.
