16Gb (512Meg×32) Low Power DDR4 SDRAM

H2AB16G32E6C uses the double data rate architecture on the Command/Address (CA) bus to reduce the number of input pins in the system. Each command uses one clock cycle,during which command information is transferred on both the positive and negative edge of the clock. To achieve high-speed operation, our H2AB16G32E6C SDRAM adopt 16n-prefetch interface designed to transfer two data per clock cycle at the I/O pins.

A single read or write access for the H2AB16G32E6C effectively consists of a single 8n-bit wide, one clock cycle data transfer at the internal SDRAM core and eight corresponding n-bit wide,one-half-clock-cycle data transfer at the I/O pins. Read and write accesses to the H2AB16G32E6C are burst oriented; accesses start at a selected location and continue for a programmed number of locations in a programmed sequence. For H2AB16G32E6C devices, accesses begin with the registration of an Active command, which is then followed by a Read or Write command. The address and BA bits registered coincident with the Active command are used to select the row and the Bank to be accessed. The address bits registered coincident with the Read or Write command are used to select the Bank and the starting column location for the burst access.
