• 1.8V + 0.1V power supply for I/O interface for -ZC25/2A
• 2.0V + 0.1V power supply for device operation for -ZC20/22
• 2.0V + 0.1V power supply for I/O interface for -ZC20/22
• 4 Banks operation
• Posted CAS
• Programmable CAS Letency : 4,5,6
• Programmable Additive Latency : 0, 1, 2, 3. 4 and 5
• Write Latency (WL) = Read Latency (RL) -1
• Burst Legth : 4 and 8 (Interleave/nibble sequential)
• Programmable Sequential/ Interleave Burst Mode
• Bi-directional Differential Data-Strobe
(Single-ended data-strobe is an optional feature).
