CMOS SGRAM
- 18
Rev. 2.4 (May 1998)
SUMMARY OF 1M Byte SGRAM BASIC FEATURES AND BENEFITS
Features
128K x 32 x 2 SGRAM
Benefits
Interface
Synchronous
Better interaction between memory and system without wait-state of
asynchronous DRAM.
High speed vertical and horizontal drawing.
High operating frequency allows performance gain for SCROLL, FILL,
and BitBLT.
Bank
2 ea
Pseudo-infinite row length by on-chip interleaving operation.
Hidden row activation and precharge.
Page Depth / 1 Row
256 bit
High speed vertical and horizontal drawing.
Total Page Depth
1024 bytes
High speed vertical and horizontal drawing.
Burst Length(Read)
1, 2, 4, 8 Full Page
Programmable burst of 1, 2, ,4, 8 and full page transfer per column
addresses.
Burst Length(Write)
1, 2, 4, 8 Full Page
Programmable burst of 1, 2, ,4, 8 and full page transfer per column
addresses.
BRSW
Switch to burst length of 1 at write without MRS.
Burst Type
Sequential & Interleave
Compatible with Intel and Motorola CPU based system.
CAS Latency
2, 3
Programmable CAS latency.
Block Write
8 Columns
High speed FILL, CLEAR, Text with color registers.
Maximum 32 byte data transfers(e.g. for 8bpp : 32 pixels) with plane and
byte masking functions.
Color Register
1 ea.
A and B bank share.
Mask Register
1 ea.
Write-per-bit capability(bit plane masking). A and B banks share.
Mask function
DQM
0-3
Byte masking(pixel masking for 8bpp system) for data-out/in
Write per bit
Each bit of the mask register directly controls a corresponding bit plane.
Pixel Mask at Block Write
Byte masking(pixel masking for 8bpp system) for color by DQi
