A novel variation-tolerant 4T-DRAM cell with enhanced soft-error tolerance
(IEEE Computer Society Publications, 2012)
Conference report
Restricted access - publisher's policyIn view of device scaling issues, embedded DRAM (eDRAM) technology is being considered as a strong alternative to conventional SRAM for use in on-chip memories. Memory cells designed using eDRAM technology in addition ... -
An energy-efficient and scalable eDRAM-based register file architecture for GPGPU
(ACM, 2013)
Conference report
Restricted access - publisher's policyThe heavily-threaded data processing demands of streaming multiprocessors (SM) in a GPGPU require a large register file (RF). The fast increasing size of the RF makes the area cost and power consumption unaffordable for ... -

Conference report
Restricted access - publisher's policyWith every process generation, the problem of variability in physical parameters and environmental conditions poses a great challenge to the design of fast and reliable circuits. Propagation delays which decide circuit ... -
Combining RAM technologies for hard-error recovery in L1 data caches working at very-low power modes
(2013)
Conference report
Restricted access - publisher's policyLow-power modes in modern microprocessors rely on low frequencies and low voltages to reduce the energy budget. Nevertheless, manufacturing induced parameter variations can make SRAM cells unreliable producing hard errors ... -
