IS43DR16128C-25DBLI

动态随机存取存储器 DDR2,2G,1.8V, RoHs 400MHz,128Mx16, IT

256Mx8, 128Mx16 DDR2 DRAM

DESCRIPTION IS43DR16128C-25DBLI

ISSI's 2Gb DDR2 SDRAM uses a double-data-rate

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 balls.

FEATURES IS43DR16128C-25DBLI

• Vdd = 1.8V ±0.1V, Vddq = 1.8V ±0.1V

• JEDEC standard 1.8V I/O (SSTL_18-compatible)

• Double data rate interface: two data transfers

per clock cycle

• Differential data strobe (DQS, DQS)

• 4-bit prefetch architecture

• On chip DLL to align DQ and DQS transitions

with CK

• 8 internal banks for concurrent operation

• Programmable CAS latency (CL) 3, 4, 5, 6, and

7 supported

• Posted CAS and programmable additive latency

(AL) 0, 1, 2, 3, 4, 5, and 6 supported

• WRITE latency = READ latency - 1 tCK

• Programmable burst lengths: 4 or 8

• Adjustable data-output drive strength, full and

reduced strength options

• On-die termination (ODT)
