VCSDRAM
(Virtual Channel SDRAM)
Manufacturer: NEC Speed:  
Year Introduced: 1997 Frequency: 143MHz
Burst Timing: CAS2 Pins: 168
Voltage: 3.3v Bandwidth:  
     The VCMemory is a memory core technology designed to improve memory data throughput efficiency and initial latency of memories. Intended for use in next generation memory systems, the VCMemory technology is ideal memory for a wide range of application such as Multimedia PC, Game machine, Internet Server etc. The slow core operation memory such as DRAM, Flash Memory and Mask ROM can get very significant performance improvements with VCMemory technology.

VCSDRAM is the first product to utilize VCM, offers the following benefits to the end user:

  • Multiplies the effective data throughput performance of conventional DRAM core.
  • Achieving close to full data bus bandwidth with low latency, interleaved random row, random column Read/Write through the channels.
  • Transparent DRAM bank operations through the concurrent foreground and Background Operations.
  • Very wide (256 bytes wide) internal data transfer bus between Channel and memory core.
  • Equivalence of tens of multiple memory banks by using only a fraction of the frequency of Row Activate and Precharge of conventional DRAM core.
