1. GENERAL DESCRIPTION
W986416DH is a high-speed synchronous dynamic random access memory (SDRAM), organized as
1M words x 4 banks x 16 bits. Using pipelined architecture and 0.175
μ
m process technology,
W986416DH delivers a data bandwidth of up to 400M bytes per second (-5). For different application,
W986416DH is sorted into the following speed grades: -5, -6, -7. The -5 parts can run up to 200
MHz/CL3. The -6 parts can run up to 166 MHz/CL3. The -7 parts can run up to 143 MHz/CL3. For
handheld device application, we also provide a low power option, the grade of -7L, with Self Refresh
Current under 400
μ
A and work well at 2.7V during Self Refresh Mode. For special application, we
provide extended temperature option the grade of -6I can work well in wide temperature from -40
°
C to
85
°
C.
Accesses to the SDRAM are burst oriented. Consecutive memory location in one page can be
accessed at a burst length of 1, 2, 4, 8 or full page when a bank and row is selected by an ACTIVE
command. Column addresses are automatically generated by the SDRAM internal counter in burst
operation. Random column read is also possible by providing its address at each clock cycle. The
multiple bank nature enables interleaving among internal banks to hide the precharging time.
By having a programmable Mode Register, the system can change burst length, latency cycle,
interleave or sequential burst to maximize its performance. W986416DH is ideal for main memory in
high performance applications.
