Features
Interface
256K x 32 x 2 SGRAM
Synchronous
Benefits
Better interaction between memory and system without wait-
state of asynchronous DRAM.
High speed vertical and horizontal drawing.
High operation frequency allows performance gain for
SCROLL, FILL, and BitBLT.
Pseudo-infinite row length by on-chip interleaving operation.
Hidden row activation precharge.
High-speed vertical and horizontal drawing.
High speed vertical and horizontal drawing.
Programmable burst of 1, 2, 4, 8 and full page transfer per
column address.
Programmable burst of 1, 2, 4, 8 and full page transfer per
column address.
Switch to burst length of 1 at write without MRS.
Compatible with Intel and Motorola CPU based system.
Programmable CAS latency.
High speed FILL, CLEAR, Text with color registers.
Maximum 32-byte data transfer (e.g., for 8bpp: 32 pixels) with
plane and byte masking functions.
A and B bank share.
Write-per-bit capability (bit plane masking). A and B bank
share.
Byte masking (pixel masking for 8bpp system) for data-out/in.
Each bit of the mask register directly controls a corresponding
bit plane.
Byte masking (pixel masking for 8bpp system) for color DQi.
