Density: 8Gb Organization: 512Mx16 Speed: PB, RC Package: 96FBGA
The 8Gb DDR4 SDRAM B-die is organized as a 64Mbit x 16 I/Os x 8banks device. This synchronous device achieves high speed double-data-rate transfer rates of up to 2666Mb/sec/pin (DDR4-2666) for general applications. The chip is designed to comply with the following key DDR4 SDRAM fea-tures such as posted CAS, Programmable CWL, Internal (Self) Calibration, On Die Termination using ODT pin and Asynchronous Reset . All of the control and address inputs are synchronized with a pair of exter-nally supplied differential clocks. Inputs are latched at the crosspoint of dif-ferential clocks (CK rising and CK falling). All I/Os are synchronized with a pair of bidirectional strobes (DQS and DQS) in a source synchronous fash-ion. The address bus is used to convey row, column, and bank address information in a RAS/CAS multiplexing style. The DDR4 device operates with a single 1.2V (1.14V~1.26V) power supply, 1.2V(1.14V~1.26V) VDDQ and 2.5V (2.375V~2.75V) VPP. The 8Gb DDR4 B-die device is available in 96ball FBGAs(x16).
