4194304-BIT (1048576-WORD BY 4-BIT) CMOS STATIC RAM
DESCRIPTION
The M5M54R04J is a family of 1048576-word by 4-bit static PIN CONFIGURATION (TOP VIEW)
RAMs, fabricated with the high performance CMOS silicon gate
process and designed for high speed application.
The M5M54R04J is offered in a 32-pin plastic small outline J-
lead package(SOJ).
These device operate on a single 5V supply, and are directly
TTL compatible. They include a power down feature as well.
FEATURES
• Fast access time M5M54R04J-12 •••• 12ns(max)
M5M54R04J-15 •••• 15ns(max)
• Low power dissipation Active •••••••••• 450mW(typ)
Stand by •••••••••• 5mW(typ)
• Single +5V power supply
Fully static operation : No clocks, No refresh
• Common data I/O
• Easy memory expansion by S
• Three-state outputs : OR-tie capability
• OE prevents data contention in the I/O bus
• Directly TTL compatible : All inputs and outputs
