Abstract
The invention is a monolithic video random access memory (VRAM) chip that has more than one write control pin which is used to segment the VRAM into banks or sub-chips having four DQ planes such that a nibble of data can be written to the VRAM. Using the method of the invention a first bank may be written independently of a second bank, such that during a single memory cycle the first bank may be written and the second bank may be read. Using the circuit of the invention data is transferred in response to an internal write signal. The VRAM of the invention functions without the masking of a write to either bank. In addition the write memory function can be performed either through the random access memory port or through the serial access memory port.
