• Manufacturer Part Number: AS7C332MFT18A-10TQC
• Description: 3.3V 2M x 18 Flow-through synchronous SRAM
• Manufacturer: ALSC [Alliance Semiconductor Corporation]

Synchronous truth table
1 X = don’t care, L = low, H = high
2 For WRITE, L means any one or more byte write enable signals (BWa or BWb) and BWE are LOW or GWE is LOW. WRITE = HIGH for all BWx, BWE,
GWE HIGH. See "Write enable truth table (per byte)," on page 6 for more information.
3
4 ZZ pin is always Low.
For write operation following a READ,
