Abstract
An integrated memory circuit in which memory cells are arranged in rows and columns, each column having a separate sense amplifier. The memory columns can be coupled to neighboring memory columns by additional transistors and the gain of the sense amplifiers in the even and the odd columns is adjustable. Consequently, information can also be serially shifted from one column to another, so that the information can be written and read not only in parallel but also serially.
