3 / 51 page KM4132G271B CMOS SGRAM - 3 - Rev. 2.4 (May 1998) The KM4132G271B is 8,388,608 bits synchronous high data rate Dynamic RAM organized as 2 x 131,072 words by 32 bits, fabricated with SAMSUNG's high performance CMOS technol- ogy. Synchronous design allows precise cycle control with the use of system clock. I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable burst length, and programmable latencies allows the same device to be useful for a variety of high bandwidth, high perfor- mance memory system applications. Write per bit and 8 columns block write improves performance in graphics systems. • JEDEC standard 3.3V power supply • LVTTL compatible with multiplexed address • Dual bank / Pulse RAS • MRS cycle with address key programs -. CAS Latency (2, 3) -. Burst Length (1, 2, 4, 8 & full page) -. Burst Type (Sequential & Interleave) • All inputs are sampled at the positive going edge of the system clock • Burst Read Single-bit Write operation • DQM 0-3 for byte masking • Auto & self refresh • 16ms refresh period (1K cycle) • 100 Pin PQFP, TQFP (14 x 20 mm) • Reverse Type Package offers the best signal routing Graphics Features • SMRS cycle. -. Load mask register -. Load color register • Write Per Bit(Old Mask) • Block Write(8 Columns) GENERAL DESCRIPTION FEATURES FUNCTIONAL BLOCK DIAGRAM 128K x 32Bit x 2 Banks Synchronous Graphic RAM CLK CKE CS RAS CAS WE DSF DQMi BLOCK WRITE CONTROL LOGIC DQi 128Kx32 CELL ARRAY 128Kx32 CELL ARRAY SERIAL COUNTER COLUMN ADDRESS BUFFER ROW DECORDER BANK SELECTION ADDRESS REGISTER REFRESH COUNTER ROW ADDRESS BUFFER MASK REGISTER COLOR REGISTER MUX WRITE CONTROL LOGIC COLUMN MASK (i=0~31) DQMi CLOCK ADDRESS(A0~A9) DQMi • • • ORDERING INFORMATION * ~G271BQR# / ~G271BTQR# : Reverse Type Package Part NO.
