IS43LD32128B - ISSI

IS43LD32128B 4Gb (x32) Mobile LPDDR2 S4 SDRAM

AUGUST 2023 The IS43/46LD32128B is 4Gbit CMOS LPDDR2 DRAM. The device is organized as 8 banks of 16Meg words of 32bits. This product uses a double-datarate architecture to achieve high-speed operation. The double data rate architecture is essentially a 4N prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O.
