K4S643233H - F(H)E/N/G/C/L/F
Mobile-SDRAM
512K x 32Bit x 4 Banks Mobile SDRAM in 90FBGA
FEATURES
GENERAL DESCRIPTION
• 3.0V & 3.3V power supply.
The K4S643233H is 67,108,864 bits synchronous high data
rate Dynamic RAM organized as 4 x 524,288 words by 32 bits,
fabricated with SAMSUNG’s high performance CMOS technology. Synchronous design allows precise cycle control with the
use of system clock and I/O transactions are possible on every
clock cycle. Range of operating frequencies, programmable
burst lengths and programmable latencies allow the same
device to be useful for a variety of high bandwidth and high performance memory system applications.
• LVCMOS compatible with multiplexed address.
• Four banks operation.
• MRS cycle with address key programs.
-. CAS latency (1, 2 & 3).
-. Burst length (1, 2, 4, 8 & Full page).
-. Burst type (Sequential & Interleave).
• EMRS cycle with address key programs.
• All inputs are sampled at the positive going edge of the system
clock.
• Burst read single-bit write operation.
• Special Function Support.
-. PASR (Partial Array Self Refresh).
-. Internal TCSR (Temperature Compensated Self Refresh)
• DQM for masking.
• Auto refresh.
