Programmable CAS Write Latency(CWL)=9,11 (DDR4-1600), 10,12(DDR4-1866),11,14 (DDR4-2133),12,16(DDR4-2400),14.18 (DDR4.2666)and 16.20(DDR4-3200)
8-bit pre-fetch
Burst Length: 8, 4 with tCCD = 4 which does not allow seamless read orwrite [either On the fiy using A12 or MRS]
Bi-directional Differential Data-Strobe
Internal (self) calibration: Internal self calibration through ZQ pin
(RZQ: 240 ohm±1%)
The 8Gb DDR4 SDRAM C-die is organized as a 64Mbit x 16 l/Os x 8banksdevice. This synchronous device achieves high speed double-data-ratetransfer rates of up to 3200Mbsecpin (DDR4-3200) for general applications.
The chip is designed to comply with the following key DDR4 SDRAM features 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 externally supplied differential clocks. Inputs are latched at the crosspoint of dif.ferential clocks (CK rising and CK falling). All l/Os are synchronized with apair of bidirectional strobes (DQS and DQS) in a source synchronous fash.ion. The address bus is used to convey row, column, and bank addressinformation in a RAS/CAS multiplexing style. The DDR4 device operateswith a single 1.2V(1.14V-1.26V)power supply, 1.2V(1.14V~1.26V) VDDOand 2.5V(2.375V-2.75V)VPP.
The 8Gb DDR4 C-die device is available in 96ball FBGAs(x16)
