7.4.3 Memory organization
Transponders with an "Alien Higgs 3" chip have an EPC memory with a standard size of 96
Bits (12 bytes). When necessary, the EPC memory size can be expanded to 480 bits (60
bytes) in steps of 16 bits at the cost of the user memory.
The following table shows how many bytes can be added to the EPC memory and how this
affects the size of the user memory.
