Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Apparently, the described embodiments are only some but not all of the embodiments of the present application. Based on the following description, various embodiments and technical features thereof can be combined with each other under the condition of no conflict.

[0034] Considering that in the current process of reading the image data of SRAM, the two bit lines connected to the storage unit need to be precharged (to a high level) every time the driver IC reads the data of a frame, the number of times the driver IC reads data The more, the more times of precharging, the greater the power consumption, which is not conducive to reducing the power consumption of SRAM. In view of this, in the embodiment of th...

Abstract

The invention discloses a static memory and a display driving method thereof. The static memory comprises a static memory array, a latch, a multiplexer and an output circuit, wherein the latch is connected with a bit line of a memory unit, latches data of a first frame of picture in a static image and maintains a level state when the data of the first frame of picture is read; the multiplexer is connected with the latch and selects a storage unit for storing the data of the first frame picture; the output circuit is connected with the multiplexer and outputs the data of the first frame as the data of the rest frames according to the time sequence. When the data except the first frame picture is read, the bit line does not need to be pre-charged again, and the power consumption can be reduced.

Description

technical field [0001] The present application relates to the field of static storage, in particular to a static storage and a display driving method thereof. Background technique [0002] SRAM (Static Random-Access Memory, Static Random Access Memory) is one of the indispensable and important components in electronic systems. SRAM is used for temporary storage of data or instructions. It has the advantages of high speed, low power consumption, and easy embedded integration. Therefore, it is the preferred device for caching in a central processing unit (Central Processing Unit, CPU). [0003] In modern high-performance processors, the chip area occupied by SRAM has become larger and larger. In the next few years, with the explosive growth of mobile Internet, Internet of Things and wearable electronic devices, the power consumption of chips will be strictly required. And severe challenges, SRAM bears the brunt. Therefore, how to reduce the power consumption of the SRAM is a...
