Abstract
A low cost data storage and communication system is disclosed. 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 denominator of all independent operating voltage ranges of all of the cards connected to the system. In addition, a novel feature of partitioning the memory storages of the card is also disclosed. 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 combination of memory groups in the card.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
