Abstract (en)
[origin: EP0462708A2] A Video Random Access Memory device wherein full and efficient use of a serial access memory portion provides a simple and efficient means of avoiding Mid-Line Reloads and Real-Time Data Transfers whereby selected parts of two different rows in a random access memory portion are transferred simultaneously to the serial access memory portion via addressable transfer gates under the control of address/control logic. <IMAGE>
