Every LTO cartridge has a cartridge memory chip inside it. It is made up of 511, 255, or 128 blocks of memory, where each block is 32 bytes for a total of 16&nbsp;KiB for LTO-6 to 8; 8&nbsp;KiB for LTO-4 and 5; and 4&nbsp;KiB on LTO-1 to 3 and cleaning cartridges.<ref name="fujispecs"/> This memory can be read or written, one block at a time, via a non-contacting passive 13.56&nbsp;MHz RF interface. This memory is used to identify tapes, to help drives discriminate between different generations of the technology, and to store tape-use information. Every LTO drive has a cartridge memory reader in it. The non-contact interface has a range of 20&nbsp;mm.<ref name="LTO-CM_13.56_MHz"/> External readers are available, both built into tape libraries and PC based. One such reader, Veritape, connects by USB to a PC and integrates with analytical software to evaluate the quality of tapes.<ref name="veritape"/> This device is also rebranded as the Spectra MLM Reader<ref name="Spectra MLM"/> and the Maxell LTO Cartridge Memory Analyzer.<ref name="Maxell-LTO"/> [[Proxmark3]] and other generic RFID readers are also able to read data.<ref name="proxmark"/>
