`ABSTRACT
`(57)
`A low cost data storage and communication system. The low
`cost data storage and communication system has a host and
`at least one card connected to the host. A voltage negotiator
`located in the system for determining a common operating
`voltage range that is a common demonminator of all inde
`pendent operating voltage ranges of all of the cards con
`nected to the system. In addition, there is a novel feature of
`partitioning the memory storages of the card. This feature
`provides the host the ability to simultaneously erase any
`combination of sectors in a single erase group, or any
`combination of the entire erase groups. Another feature
`feature provided by this novel method of partitioning the
`memory storages is the ability to write protect any combi
`nation of memory groups in the card.
