260Pin DDR4 2400 SO-DIMM 16GB Based on 1Gx8 Pin Identification Symbol A0-A16 BA0, BA1 BG0, BG1 RAS_n CAS_n WE_n CS0_n, CS1_n CKE0, CKE1 TS16D42AR00SNS Description DDR4 SO-DIMMs are high-speed and low power memory modules that use 1Gx8bits DDR4 SDRAM in FBGA package and a 4K-bit serial EEPROM on a 260-pin printed circuit board. DDR4 SO-DIMMs are dual In-Line ODT0, ODT1 memory modules and are intended for mounting into ACT_n DQ0-DQ63 CB0-CB7 260-pin edge connector sockets. The synchronous design allows precise cycle control with DM_n/DBI_n/ the use of system clock. Data I/O transactions are possible on both edges of DQS. The large range of DQS0_t-DQS8_t operation frequencies and programmable latencies allow DQS0_c-DQS8_c the same device to be useful for a variety of high bandwidth and high performance memory system CK0_t, CK1_t applications.
