DRAM

FEATURES

• Industry-standard x4 pinout, timing, functions,

and packages

• High-performance, low-power CMOS silicon-gate

process

• Single power supply (+3.3V ±0.3V or +5V ±0.5V)

• All inputs, outputs and clocks are TTL-compatible

• Refresh modes: RAS#-ONLY, HIDDEN and CAS#-

BEFORE-RAS# (CBR)

• Optional self refresh (S) for low-power data

retention

• 11 row, 11 column addresses (2K refresh) or

12 row, 10 column addresses (4K refresh)

• FAST-PAGE-MODE (FPM) access

• 5V tolerant inputs and I/Os on 3.3V devices

NOTE: 1. The 4 Meg x 4 FPM DRAM base number differenti-

ates the offerings in one place—MT4LC4M4B1. The

fifth field distinguishes various options: B1

designates a 2K refresh and A1 designates a 4K

refresh for FPM DRAMs.

2. The # symbol indicates signal is active LOW.

*Contact factory for availability
