MT42C4256C-10/883C AUSTIN [Austin Semiconductor], MT42C4256C-10/883C Datasheet - Page 27

• Manufacturer Part Number: MT42C4256C-10/883C
• Description: 256K X 4 VRAM 256K x 4 DRAM with 512K x 4 SAM
• Manufacturer: AUSTIN [Austin Semiconductor]

NOTES:
1. Access time is t
2. Output can go from the high-impedance state to an invalid data state prior to the specified access time.
NOTE A: A write cycle or a read-modify-write cycle can be mixed with the read cycles as long as the write and read-modify-write timing specifications
are not violated and the proper polarity of DSF is selected on the falling edges of RAS\ and CAS\ to select the desired write mode (normal,
block write, etc.)
