Abstract
The integrated circuit memory comprises a memory array including a plurality of memory cells in rows and columns, the memory array being divided into a plurality of blocks of the memory cells. Each of the blocks includes a plurality of word lines arranged along the rows and coupled to the memory cells, a plurality of first and second bit lines alternately allocated along every other column, a first selecting line for providing a control signal, a second selecting line for providing the control signal, a plurality of first selecting transistors having their gates coupled to the first selecting line to receive the control signal, each of the first selecting transistors for coupling one of the memory cells in a selected row to one of the first bit lines in response to the control signal, two of the first selecting transistors being coupled to a same one of the first bit lines and located on opposite sides of the one of the first bit lines, and a plurality of second selecting transistors having their gates coupled to the second selecting line to receive the control signal, each of the second selecting transistors coupled to one of the second bit lines, each of the second selecting transistors for coupling one of the memory cells in the selected row to one of the second bit lines in response to the control signal.

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.
