MSM54V32126/8
131,072-Word ¥ 32-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM54V32126/8 is a new generation Graphics DRAM organized in a 131,072-word ¥ 32-bit
configuration. The technology used to fabricate the MSM54V32126/8 is OKI's CMOS silicon gate
process technology. The device operates with a single 3.3 V power supply.
FEATURES
• 131,072-word ¥ 32-bit organization
• Single 3.3 V power supply, ±0.3 V tolerance
• Refresh: 512 cycles/8 ms
• Fast Page Mode with Extended Data Out (EDO)
• Write per bit (MSM54V32128 only)
• Byte write, Byte read
• RAS only refresh
• CAS before RAS refresh
• CAS before RAS self-refresh
• Hidden refresh
• Package:
