IS43LR16800F 2Mx16 Mobile DDR SDRAM ISSI IS43LR16800F 2Mx16 Mobile DDR SDRAM is 134,217,728 bits Mobile Double Data Rate (DDR) Synchronous DRAM (SDRAM) organized as 4 banks of 2,097,152 words x 16 bits. This product uses a double-data-rate architecture to achieve high-speed operation. The Data Input/ Output signals are transmitted on a 16-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. This product offers fully synchronous operations referenced to both rising and falling edges of the clock.
