IS43LR32640B Overview
This product uses a double-data-rate architecture to achieve high-speed operation. The Data Input/ Output signals are transmitted on a 16-bit or 32-bit bus. The double data rate architecture is essentially a 2N prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins.
IS43LR32640B Key Features
- JEDEC standard 1.8V power supply
- VDD = 1.8V, VDDQ = 1.8V
- Four internal banks for concurrent operation
- MRS cycle with address key programs
- CAS latency 2, 3 (clock)
- Burst length (2, 4, 8)
