Description
The EM47FM0888SBA is a high speed Double Date
Rate 3 (DDR3) low voltage Synchronous DRAM
fabricated with ultra high performance CMOS
process containing 4,294,967,296 bits which
organized as 64Mbits x 8 banks by 8 bits. This
synchronous device achieves high speed
double-data-rate transfer rates of up to 1600
Mb/sec/pin (DDR3-1600) for general applications.
The chip is designed to comply with the following key
DDR3 SDRAM features: (1) posted CAS with
additive latency, (2) write latency = read latency -1,
(3) On Die Termination, (4) programmable driver
strength data,(5) seamless BL4 access with
bank-grouping. All of the control and address inputs
are synchronized with a pair of externally supplied
differential clocks. Inputs are latched at the cross
point of differential clocks (CK rising and /CK falling).
All I/Os are synchronized with a pair of bidirectional
differential data strobes (DQS and /DQS) in a source
synchronous fashion. The address bus is used to
convey row, column and bank address information in
a /RAS and /CAS multiplexing style. The 4Gb DDR3
devices operates with a single power supply:
1.5V±0.075V VDD and VDDQ. Available
package: FBGA-78Ball (with 0.8mm x 0.8mm ball
pitch)
