Abstract: A method, system, and computer software product for operating a memory cell collection. Memory cells in the collection store binary multi-bit values delimited by characteristic parameter bands of a characteristic parameter. In one embodiment, a comparing unit compares a retrieved count and a stored count for each binary multi-bit value. The retrieved count, equal to the number of occurrences the binary multi-bit value, is retrieved from the memory cell collection. The stored count, equal to the number of occurrences the binary multi-bit value, is stored in the memory cell collection. An error correction unit then assigns the error memory cell(s) a corrected binary multi-bit value with the characteristic parameter value within the characteristic parameter band adjacent to the characteristic parameter band associated with the retrieved binary multi-bit value such that the retrieved count of each binary multi-bit value is equal to the stored count of each binary multi-bit value.

Abstract: A method, system, and computer software product for operating a collection of memory cells. Memory cells are organized into a group of memory cells, with each memory cell storing a binary multi-bit value delimited by characteristic parameter bands. Two adjacent characteristic parameter bands are assigned binary multi-bit values that differ by only one bit. In one embodiment, an error correction unit calculates an actual parity check value of the retrieved binary multi-bit values for the group of memory cells. If the actual parity check value is not equal to the expected parity check value, the error correction unit assigns the error memory cell a corrected binary multi-bit value with the characteristic parameter value within the characteristic parameter band adjacent to the characteristic parameter band associated with the retrieved binary multi-bit value such that calculating a second actual parity check value correctly indicates the parity for the group of memory cells.

Abstract: Techniques for managing electronic mail. Folder rules for associating electronic mail messages with folders are received. The folders are managed by an electronic mail client and stored in a computer usable memory. Electronic mail messages are also received. Each of the electronic mail messages is associated with at least one of the folders according to the folder rules. Furthermore, a visibility condition is received.

A processor causes the specified folder not to be visible in the user interface when the visibility condition is not satisfied. A visibility condition may instead specify when a specified folder is not visible in the user interface. In this case, the specified folder is caused not to be visible in the user interface when the visibility condition is satisfied.

The computer program product of memory cell operation entails receiving a request to read a binary value stored in the memory cell.

The electron discharge time measurement is stopped when the voltage level in the bit-line falls below a pre-defined reference voltage. A determining operation determines the binary value from the measured electron discharge time.
