A Spare_enable signal activates the redundancy controller only when a failure address is detected. The Decoder (DEC) generates MUX_select signals, which determine whether each MAC output comes from the core row or the spare row. Under normal operation, all MUXes pass the original core outputs to the adder. When a failure address is matched, the corresponding MUX switches its input to the spare MAC row, and the Spare_bit logic ensures that only the failed row is redirected. This allows accurate delivery of MAC results with proper bit-position alignment, preserving output integrity even in the presence of retention failures. In contrast, previous methods suffer from several limitations: • Conventional redundancy schemes such as spare row/column replacement or I/O line shifting focus only on CDRT (Cell Data Retention Time) failures and cannot detect or repair MDRT-related issues. • In bit-position-sensitive MAC operations, shifting-based repair corrupts the alignment between MAC outputs and digital bit positions, leading to incorrect accumulation results. • Previous methods rely on external failure maps and lack the ability to dynamically reflect MAC-specific degradation patterns within the compute path. Therefore, the proposed approach provides in-situ MDRT repair with bit-position fidelity, overcoming both detection and precision limitations of earlier techniques. 2025-07-04 DRAM Refresh Circuit • The Adaptive Refresh Tracking (ART) mechanism dynamically adjusts refresh timing based on real-time retention behavior, minimizing unnecessary refresh operations and power overhead. ART utilizes two types of replica eDRAM cells: a Static Replica DPC (SRDPC) and a Dynamic Replica DPC (DRDPC). The SRDPC is isolated from leakage effects and provides a stable voltage reference, while the DRDPC mimics the leakage characteristics of real cells in the array. By comparing the wordline accumulation voltages (AWL) derived from these replicas, ART detects when the data degradation in DRDPC causes the analog output to deviate by more than 0.5 LSB from the SRDPC reference. At this threshold, a refresh enable signal is triggered, initiating a targeted refresh operation. To ensure conservative estimation, the DRDPC is intentionally designed with reduced capacitance, making it more sensitive to leakage. This setup enables accurate, corner-aware tracking without external sensors, achieving up to 61% refresh power reduction with only 1.56% area overhead. 2025-07-04 DRAM_PIM Decoder • The row decoder is designed to handle a 9-bit address input, allowing the selection of one out of 512 columns. To control its operation, several global signals are utilized. The Decoder_enable signal ensures that no decoder output is unintentionally activated when no valid address is present, effectively disabling all decoder outputs when needed. The Write/read enable signal determines whether the write word line (WWL) or read word line (RWL) is activated, enabling appropriate access to the cell array. For MAC operations, MAC_enable and MAC_mux signals are used to drive the MAC word line (MWL). Each subarray includes a multiplexer that enables the same cell position across subarrays simultaneously, such as cell<0>, cell<4>, cell<8>, and so on. 2025-07-04 Driver with crosstalk cancellation (차세대지능형반도체사업단) · HBM의 TX driver IP, crosstalk를 제거함 · 데이터 송신을 위한 회로 2024-08-29 처음으로 이전페이지 7 8 9 10 11 12 13 14 15 16 >다음페이지 마지막으로
